Axieinfinity
Signficance: Early pioneer with novel mechanics such as breeding. Amongst top grossing NFT projects
Editions: Not sure
"Axie Infinity is a Pokémon-inspired universe where anyone can earn tokens through skilled gameplay and contributions to the ecosystem. Players can battle, collect, raise, and build a land-based kingdom for their pets. All art assets and Axie genetic data can be easily accessed by 3rd parties, allowing community developers to build their own tools and experiences in the Axie Infinity universe. Although Axie is still in early access, Axie is ranked the #1 Ethereum game by daily, weekly, and monthly active users. It has generated over 6,400 ETH in revenue (2M+ USD) so far. While Axie is a fun game, it's also taken on characteristics of a social network and jobs platform due to the strong community and play to earn opportunities that have come from its early success. The key difference between Axie and a traditional game is that Blockchain economic design is used to reward our players for their contributions to the ecosystem. This new model of gaming has been dubbed "play to earn". Axie has attracted thousands of players from developing countries in the pursuit of a new income stream during the Covid pandemic. Many of these players are fathers, aunts, and even grandparents who have never used Blockchain technology before!" - from Axie Infinity whitepaper
