Yeah i can understand why some people don't really feel much incentive to replay echoes lol.
And corruption's backtracking is pretty silly. Though to its credit, it requieres the least endgame "key" collection since not all of them are required (mp1/mp2 have artifacts/sky temple keys). The problem I have with the energy cell collection, though, is that they're really just an afterthought; half of them are practically force-fed to you, and you only need half of them to beat the game as intended, so it's basically "...why does this exist?"
