SIDUS belongs to a new type of video game, one that implements a “play-to-earn” model. This concept gives players ownership rights over all in-game items and incentivizes them to play and progress through the game. SIDUS HEROES and other games like it, build up player-driven economic systems that have tangible value in the real world. The development of play-to-earn mechanics has given rise to the ‘Leisure Economy’, in which players make all their income in playing the games.
