Mitch Zamara is a veteran game designer who started in the free-to-play (F2P) mobile industry at Zynga and is now with Million on Mars, where he's designing an NFT-based game experience based on the colonization of Mars. The past year has seen enormous growth in the play-to-earn (P2E) segment of blockchain gaming. Since there's been plenty of coverage of games like Axie Infinity and NFT-based games in general, Mitch and I decided to the use the hour to dig deeper into issues of game design, as well as opportunities for growth. We talked about the non-blockchain origins of earning money from game-playing--which includes areas like esports, modding, etc.--and discussed how this may inform the future of P2E as it starts to blend the distinction between players and designers. We also discussed some of the game design issues for game designers thinking of making the transition from F2P (or other business models) to P2E.
