The much-hyped cryptocurrency tokens might at least shake up how games are made
The NFT-based game Axie Infinity, developed by Ho Chi Minh City–based blockchain-tech company Sky Mavis, has popularized an in-game economy based around the Ethereum blockchain.
Scam or revolution? The inexorable creep of non-fungible tokens (NFTs) into video games has polarized an ongoing debate in the cryptocurrency and gaming worlds. (Neither of which tend to be shy about sharing their opinions online.) But while some of the more ambitious claims made by NFT’s promoters seem unlikely to pan out, the technology could still shake up the relationship between gamers and developers.
NFTs build on the same underlying blockchain technology as cryptocurrencies, but while any two bitcoins can be exchanged like-for-like, each NFT is unique. These tokens can therefore be used as a certificate of ownership for digital items, which is both easily verifiable and impossible to fake thanks to the cryptographic underpinnings of blockchain technology. The technology hit the mainstream last year and since then NFTs linked to digital images, GIFs, videos, and tweets have been going for millions of dollars apiece, with total sales in 2021 topping US $25 billion.
But while the NFTs themselves are unique, the digital items they assert ownership over can be easily copied or downloaded. This has led to claims they have no inherent value and the market is driven by speculation. Their environmental impact has also been criticized due to the processing requirements of some blockchains, although more eco-friendly options do exist.
NFT advocates “get wrapped up in the technologies of ownership and how markets will work. That’s just not the source of value in games.”

More recently, the technology has been muscling into the game industry with both a new breed of blockchain game companies and established developers extolling their virtues. NFTs might seem like a more natural fit for gaming than digital art, as they can be attached to unique in-game items—such as outfits or weapons—which can actually be used by their owners and are not easy to copy in the way a JPEG is. So far, the reaction from gamers has been largely hostile though, with many criticizing the technology as a way to extract more money from players. But advocates say it gives gamers a way to truly own their digital items and sell or trade them, without being beholden to the whims of a particular app store or game publisher.
“They’re the perfect vehicle to store unique game data that players should be able to own and use, potentially across other experiences,” says Aleksander Larsen, the cofounder of Sky Mavis, which produces popular NFT game Axie Infinity. As gamers play various titles, they can accrue NFTs linked to costumes, weapons, characters, and achievements, he says, which they can either decide to sell on once they are done with a game or retain as unique collectibles.
By linking game items with the wider blockchain ecosystem, NFTs also give developers instant access to powerful financial capabilities, says Larsen. Some games have leaned into this to create a new gaming model known as “play-to-earn” with Axie the poster child for the approach. Players buy NFTs of monsters that can be battled against each other to earn cryptocurrency or bred to create new NFT monsters to sell or rent out to other players. Sky Mavis takes a cut of all transactions, but Larsen says the approach allows gamers to capture some of the value created in the virtual world. “We’re trying to make the pie bigger by sharing parts of the revenue,” he says.
Despite the excitement though, Edward Castronova, a professor of media at Indiana University Bloomington who specializes in the economies of virtual worlds, says there’s nothing especially new about these ideas though. Games like World of Warcraft and Runescape, among others, have long allowed players to trade valuable in-game items, and while they don’t have direct routes to monetization, third party sites make it possible to buy and sell loot for real money.
Xavier Coelho-Kostolny, a 3D-character artist, compares the NFT-gaming craze to taking a cup holder from a BMW and trying to put it in a Honda Civic.
The technology would improve the transparency and security of these in-game economies, while providing easier access to sophisticated trading features, says Castronova. But he thinks it’s an incremental improvement at best. And while NFTs could potentially enhance already entertaining games, he thinks more often than not they’re a distraction that causes developers and investors to lose sight of what matters to customers.
“They get wrapped up in the technologies of ownership and how markets will work”, he says. “That’s just not the source of value in games.” People play games to have fun, he says, and unless adding NFTs improves the gameplay, they aren’t adding any real value. The failed attempt to introduce an auction house into the game Diablo III, which allowed payers to sell items for real money, demonstrates how trading dynamics can easily make a game worse rather than better.
One of the most alluring claims made by proponents of NFTs in games is that they could potentially facilitate the transfer of in-game items between different titles. This was one of the justifications for Ubisoft’s poorly received release of a collection of NFTs for its Ghost Recon Breakpoint game.
But while in principle, NFTs are a good way to manage ownership across separate gaming ecosystems, the technical challenge of actually transferring items between them means its little more than a pipe dream, says Xavier Coelho-Kostolny, a 3D-character artist at Magnopus, who has worked on triple-A games. He compares it to taking a cup holder from a BMW and trying to put it in a Honda Civic. “The Honda Civic doesn’t have the structural supports, it doesn’t have the general shape, the materials are all wrong, it’s probably going to look weird because the style of the cars are wrong,” he says.
But an NFT does give contributors to a crowdfunded game project something of immediate value that they can trade on the open market. That could still be significant.
Many game studios use bespoke software that differs in everything from 3D file formats, to how material textures are rendered to underlying physics. Unreal and Unity, the two biggest commercially available game engines, can’t even agree on whether up and down are denoted by the y- or z-axis, says Coelho-Kostolny. While there are efforts to build open standards for virtual worlds, they are still at an embryonic stage. The legal headaches involved in allowing one company’s intellectual property to appear in another company’s game would also be enormous, adds Coelho-Kostolny. And it’s far from clear what incentives exist for a developer to build support for an item it won’t make money from.
Larsen agrees interoperability between games is a distant dream, and he recognizes that NFT games can’t be all about the trading. A sizable proportion of Axie users play specifically to earn money, and that’s something they are trying to change. “We think the game needs to be more fun,” he says. “That’s the basis of anything to make it sustainable.” But he says that the excitement around NFTs has allowed the game to grow far faster than would have otherwise been possible, and he believes the approach presents a novel growth model for smaller developers. Giving people a way to take part ownership in a game also creates an entirely new dynamic between players and developers. “They are actually co-growing the game with you,” he says.
NFTs, in other words, provide a more flexible way for small developers to crowdsource funds, says Paul Gadi, chief technology officer of OP Games. Without NFTs, a game developer on a crowdfunding campaign might resort to in-game Kickstarter premiums that can only be delivered once a game’s development cycle is fully completed. However, with NFTs attached to these premiums—that exist independently of the game itself—the developer can provide something of immediate value that can be collected and traded on the open market. The technology could even help create more concrete connections between players and developers through decentralized autonomous organizations, or DAOs. These are groups of people who collaborate on a project without a central hierarchy based on rules encoded in smart contracts on the blockchain. Decisions are made by votes and voting rights can be assigned based on NFT ownership. These could still be significant developments in gaming technology.
“What would games look like if games were collaboratively designed with the players?” says Gadi. “And what would it look like if the NFTs were used as a way to govern the game development?”

A pioneering female engineer fought hard for her colorful creature
Dona Bailey, who recently left Atari and joined Videa Inc., is apparently the only woman who designs coin-operated games in the United States today, though a few other women design home games. Centipede was her first attempt, and it was a smashing success. She attributes it to beginner’s luck, a series of accidents, and intuition.
“When I got to Atari, everyone was doing a space game or a war game,” she said. “I didn’t want to do either. I thought games could be more attractive, but I didn’t know what to do, so I didn’t say anything. I was supposed to do a laser game, and I didn’t want to do it.”
“Atari kept a notebook of game ideas, and there was one sentence—a multisegmented worm comes out, gets shot at, and breaks into pieces—that I kept coming back to. It wasn’t that a worm was attractive, but it was the only different idea in the whole book. So when a few people said maybe we shouldn’t do another laser game, I said, ‘Did you see that worm?’”

This article was first published as “Centipede: the worm that turned a trend.” It appeared in the December 1982 issue of IEEE Spectrum as part of a special report, “Video games: The electronic big bang.” A PDF version is available on IEEE Xplore.
“Designing Centipede—it was always called Centipede—was a logical progression; nothing got taken out once it got put in, which is rare. For example, I wanted to make sure I was turning the centipede in the right places as it moved across the screen, so I put some visual markers in to help me program—just little dots. People came in and said the dots were really dumb, and I should make them rocks. I never intended to leave them in, but it made the screen a maze, and it was better. I didn’t like the idea of rocks, so I started fooling around with graph paper and came up with the mushrooms.
“Then I wanted something that was more threatening to the player, something that came close to the bottom of the screen. I thought of a spider, because I’ve always been scared of spiders—when I see a spider I think it’s coming to get me. I did the spider over the Thanksgiving holidays. And I fooled around trying a bunch of different movements for a week.
“They were all crummy. Then I hit on the idea of making the spider bounce up and down—it looked like bouncing on one thread of a web. I was so happy.”
Except for the spider, the sounds of Centipede were done by Ed Logg, a designer at Atari. “All the sounds were deep,” Ms. Bailey said. “I wanted something higher-pitched so I did it.”
“Since Centipede did so well, Atari has started seeking designers who are into things other than space and war.”
Reviews of the game Centipede focus on the “incredible colors” that stand out; they were different from anything in arcades. “At first Centipede was black and white,” Ms. Bailey recalled, “but Missile Command came out eight months earlier, and it had colors, so I wanted colors. I argued for a long time and finally got the eight standard primary colors. I said that wasn’t enough. I wanted more colors, like purple, because there was a fashion craze then for purple, and I was always wearing purple and brightly colored clothes. They never had a female programmer before, and they teased me as if I were from a different planet.
“I kept asking for different colors, and only my technician would listen. He came up with a different set of really bright colors, but I wanted some pastels. One day he was standing behind the cabinet, tweaking the resistors, and by accident he hit on an astounding set of colors. I said, ‘Stop!’ He hated the colors and wanted to change them back, but I wouldn’t let him. For days I sat around playing with new color combinations. People would come look and say, ‘Blah!’ Even after it did well, the other designers kept saying ‘Blah!’ but women tell me they like the colors.”
Another thing reviewers like is the simple trackball control used to play Centipede. “They didn’t want me to use a trackball,” Ms. Bailey explained. “Ed was really big on buttons. He thought if you give people enough buttons to keep their hands busy, they’ll be happy. I thought that with all those buttons, I wasn’t going to be able to play it—I never could play Missile Command or Defender—and I had to play it to program it. On top of that, people who looked at the game thought I might be designing a little kids’ game—and little kids can’t handle a lot of buttons.
“For a while it had a joystick, but that was awkward, and I think controls should be natural. I finally convinced them to try a trackball, just so I could use it while I was working—the game was produced with a trackball.
