Stay? is a pretty ambitious time-loop game: you may not find it successful at all the things it tries to do but its whole point is both different paths through and different endings, and you probably won’t see all of them unless you really work at it (and maybe not even then).
And of course if you want to spend money, anything from Choice of Games fits that pattern too: Choice of Robots is popular, or Brian Rushton wrote about Crème de la Crème recently.
