I'd like to think I'm not the only person who has done this, but there are some games that, for whatever reason, I've loved playing through but known full-well at the same time I would never play through again. I generally play through games I really like multiple times, so for a game to make me react this way to it is a bit of an oddity for me but not unheard of. There's also been certain parts of games I've enjoyed greatly but would never want to touch again for varying reasons, which would either put me off playing through the game again entirely if unavoidable (although I doubt I'd like the part in question if it made me react this way) or just make me avoid that part of the game ever again. As far as individual games go, most RPGs would come under this due to their length but Earthbound probably fits the bill best. I really enjoyed Earthbound when I played it at uni, but part of the reason why I wouldn't ever play it again is simply because I don't remember much of the game at all now. While this may be a reason to many to play it again, since it'd feel like a fresh experience, to me it effectively leaves me no reason to ever touch it again since I can't vividly remember why I enjoyed it in the first place, but at the same time I've already played and beaten it so there's nothing really new there either. As for specific parts of a game, Destiny's King's Fall raid is one of the best areas I've ever played through in any game. I'd go as far as to say that King's Fall is better than any of World of Warcraft's raids, and I played that game for years and enjoyed it greatly too. The bosses were awesome to fight against, especially the final fight against Oryx which to me is the best raid boss ever made, but two things stand out that would make me never want to play through King's Fall again. The first problem is a jumping sequence near the start of the raid that is an absolute nightmare to navigate unless you know the correct route to jump across the Hive Tombships already, otherwise you can have fun getting repeatedly killed as you just miss the wrong ship or spend too long trying to work out where to go next only to have the Tombship you're stood on teleport out from under you and drop you to your death. Another jumping sequence two bosses after this one is significantly less irritating to deal with than this one. The biggest problem however is trying to find a group to do the raid; it can't be done alone and trying to find five other players competent enough to get through the raid's challenges ends up being harder than the raid itself, and unless you're part of a Destiny clan or happen to have five or more readily available friends to do the raid with, trying to do this raid regularly will be far more trouble than it's worth despite how good it is. I will say though that anyone who plays this game should definitely play through the raid at some point even if it is only once, because the good parts of it have to be experienced. Any games or levels you liked but would never want to touch again?
