Calling Resident Evil 5 complex is such a weasel worded way of describing the thing. The game is deeply racist to its core, one of the most tasteless stories I've seen in a long time. Yet, strictly as a mechanical entity, I cannot deny it was quite fun. I played the whole game co-op with a friend, probably a requirement for the game to be any fun, as its clearly the way the entire game is designed around. Some of the boss fights and more challenging bits seem like they would be truly awful with an AI to babysit. The game is a little dated (and not just because of the sub 1800s racism), the cutscene QTEs chief among them. But the set pieces feel suitably spectacular, the stop and pop gameplay makes every encounter feel the right amount of tense and the levels are paced suitably for the mechanics. It makes this game a weird one to chew on. IF you have a friend willing to play through the entire thing with you and IF you both are willing to reckon with how offensive the game is, then i can't say I didn't enjoy playing it. But i can't really recommend it unless you meet those criteria. Maybe just play 4? That one I've heard is pretty good.
