Recently there have been a few monster collector games that have popped up to compete with Pokémon. There's have Temtem which is a 3D adventure where you travel across the Airborne Archipelago collecting and battling creatures called Temtem to become the best Temtem tamer. It's currently in Steam Early Access. More recently is Coromon which is a retro style adventure where you battle and collect Coromon and fight powerful titans. It currently has a demo on Steam. I think both seem promising in their own way and having competition for Pokémon should give them more incentive to improve. What do you think?
