So, in summary, single, dual, or triple token models are irrelevant if the game's sink and sources are not thoroughly considered + target demographic + game objectives.  Personally, I favor a dual or triple token model that separates investor and player incentives.

StepN isn't a P2E. It's a social fitness app. Different user demographic.  Running is a perpetual activity for those who wish to keep themselves fit.  Hence, StepN's base players are more sticky compared to other games.

Game's sources and sinks are CRITICAL to develop a healthy economy of a game, both web2 and web3.It helps to shape a sticky user's behavior, and, of course, affects user attraction and retention.
