>>47625702>>47625781You absolutely can do an open-world Pokemon game, it's just what romhackers forget or outright can't implement because of the effort and time required is to actually make the world worth exploring. CC and ROWE lack side-quests, an actual plot, the routes by themselves tend to be really tiny with nothing to do besides just walking past them, etc.
The problem plaguing Pokemon OWs is the same one with bad OWs in general, there's nothing to do in them.
