I need to know all the games like that

Without spoilers. There is a runback to an arena fight before a boss in act 2 and it is insanely hard and fun. It is optional though I don't know if it is requires to get true ending. Silksong pulling me back to MH.

So true, I only played act 1 so far. But I can see that it is coming from a real CAG fan. You can taste and smell all the passion for genre.
