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
Toy Commander on Dreamcast was really really fucking good for its time and something like it with 256 players doing all sorts of crazy shit in a sandbox household flying/driving/swimming vehicles around all over the place would be incredibly fun.
Nobody has made literally anything like it since and I have no idea why because the concept is obviously good and the technology to realise it to its fullest potential didn’t exist back then but it was still such a good game.
