A memorable New Game + experience is (or I guess was to some degree) Dark Souls II, because, they did more than just let you keep your gear and levels, and bumped up the difficulty in a general sense by making enemies stronger. There was some item placement switcheroos if I remember correctly, and some items and upgraded versions of accessories that could only be found in NG+.
The main change, though, was that there was a fairly extensive overhaul of the enemy placements in a lot of the game’s areas. Funny escalations like added ambushes or a very hard enemy hanging out in one of the very early areas to keep you on your toes. It didn’t exactly let you play the game all over again but it did give you something to entice you into doing it, just to see what is different and to see if it will be able to Dark Souls style fuck with you all over again.
However, I say that Dark Souls II’s New Game+ was a memorable experience rather than is, because the Scholar of the First Sin edition of the game just replaced the original enemy placements with the New Game+ version. There is some contention over whether the second layout is more of an improvement rather than something really all that new, and it has been way too long for me to remember how they really compare, but it is kind of weird that for a lot of players they completely removed the option to play the game one way and then play it another, which was a big part of its charm.
At any rate, I’m far from the most zealous Dark Souls II defender, but this is unequivocally something Dark Souls II does that is special and is sorely missed from the other games, which for the most part just apply some multipliers to health and damage variables and largely otherwise call it a day. #darksouls2crew (miss u @Syzygy)
