I do a bit of both tbh.
Usually, new but if I'm looking for an older game I gotta go with pre owned.
Matter of fact I gotta buy an old copy of Digimon World 3 here soon enough
both
if im buying a game thats still pretty new i probably wont bother to look for a preowned version since its barely cheaper anyway. otherwise i usually look for preowned, it doesnt change the game at all so why care.
if it's an old game then i'd rather buy it pre-owned bc if it's brand new then older/classic games sell for 100 dollars or some s**t nd i dont got that kind've money lmao
