I have been looking at different mobile game developers' Play Store pages and noticed their entire game libraries are all free or all paid, with free games being a “demo”. I plan on making cross-platform games on Steam and mobile, as well as a few free-to-play mobile games with ads and IAP, all of them Simulation/RPG games with the same graphics style (3D models with PBR textures). Is offering both freemium games and paid games a good business model, even if the freemium games are only on mobile and the paid games on many different platforms?
NOTE: Along with games, I also plan on making a gamified education platform that is basically an open-world sandbox-type game combined with an education website. Either this or a freemium game witll be the game I start with when starting my own game company.
