One I haven’t seen mentioned (at a glance at least) is Noita.
Getting the “false ending” is achievable with some effort, but I dare you to actually finish the game. And as far as replayability, you’ll be hard pressed to have two runs that go the same. The amount of Butterfly Effect in this game from all the combinations and systems is straight up insane.
On the bright side though, they are consistently updating the game. I don’t play, but several of my friends play it all the time, and to them it definitely seems to be worth what they paid.
