Popped up at least 5 times from my recollection, and that's just what I noticed, I don't read the whole forums.
Just to clarify, my dislike (which isn't actually dislike, I like the game but I have some problems with it) for Braid has nothing to do with not being "indie" enough or whatever. I don't care about that stuff.
OK, I think it's time to stop being vague and actually explain myself:
See, Braid is basically a perfect game. It takes a simple-but-clever concept and executes it almost flawlessly. The puzzles are superbly designed, the difficulty is smooth, the freedom in choosing levels minimizes frustration, the game creates a unique atmosphere with its art and music. The problem for me was that, despite (or perhaps because) of the fact that it's an absolute marvel from a design standpoint, I just didn't enjoy actually playing
it that much. Or you could say it's a game I admire more than I enjoy it. I could never really get out of "analytical mode" and actually have fun with it. I experienced it almost as an interactive lesson in game design ("That's a clever mechanic", "I see what he was going for here", etc.).
I hope that makes sense.
