It’s slightly uncanny wandering around or playing back through levels after finishing the main campaign. Feels a bit like strolling round a graveyard.
Most of the challenge has gone because you’re pretty much a level 9000 super tank, and any traps or puzzles you’d encountered earlier aren’t a threat anymore.
But there’s some that have genuine replay value isn’t there? Post them below.
Pretty much every paradox grand strategy game.
It’s usually the end of the game by the time you understand the basic rules and several more before you have a grasp on the rest.
GTA v springs to mind. Best place for going on a murderous rampage when the mood takes you, all things considered
Plus also most of the actual missions are a bit tedious
Path of Exile. The campaign is basically a tutorial and the end game is the actual game.
Most recent Super Mario games
Hollow Knight
Resident Evil 4, sort of - really fun going through the game again when you can merk everything in sight with a rocket launcher
I don’t think there are any, at least not for me. Once I finish the story/all the levels, the thrill is gone, I really couldn’t care less what super weapon or outfit where I get to look like a toilet I get.
I will both agree with this and also ridicule it by saying exactly the same principle applies to plants vs zombies
maybe the closest is something like Streets of Rage 4 where it’s pretty short (2-3 hours) and you can play a higher difficulty and just learn to get better at the mechanics
Without wanting to sound unkind you do have a very specific taste in computer games
Really disappointing when the ‘‘true’’ or good ending can only be accessed after a second/third playthrough.
Unless it’s like a core mechanic of the game and things are slightly different, but in most of the classic horror games playing the exact same game again is just mandatory. NOT OKAY.
I think I enjoyed my NG+ (and ++, and +++) runs of Sekiro more than the first time through. Really nice absolutely tearing through bosses that took me hours and multiple tries the first time. Think my last playthrough was about 4 hours long. 
weird in games like Diablo and the like where the point is to finish the story as quickly as possible and then grind endgame dungeons hundreds of times to get a better weapon, like the people who love those games don’t care if the campaign is crap it’s just a tutorial
Super mario odyssey puts the best parts of the game behind the final boss.
Oh maybe the answer is Tekken 3 because eventually you would unlock Tekken Volleyball mode and loads of great characters
yeah maybe this is one of the best answers, Mario games usually have the most engaging levels after the ending
the meat of Hades is after escaping, does that count?
I would say that isn’t yet finishing the story/campaign but sure!
