for me its dragon ball z. i’ve always wanted a good 3d open world dbz action rpg kind of game, but it’s just never been done to its full potential. the closest we’ve gotten in my opinion is dragon ball z kakarot, which has great DBZ fighting game style fighting, and tries to incorporate it with an open world with rpg-light type features, but the world and rpg elements are just so uninspired and poorly done. they don’t really blend well with the fighting segments either, it feels like all of the ‘open world’ is more of just a 3d overworld with minigames
Mount and blade style would work as well, assuming the first book. A paradox style prequel would also work. A frostpunk style leadership game/ hard space mining game for the reds. It has tons of potential for many types of game even within genres.
