As you know by now, I love the Galaxy games and they're not only my favorite Mario games but my favorites of all time (and I worship Rosalina).
For Mario 64, guess we'll have to agree to disagree since the controls didn't age imo. I can see your reasoning though.
My other favorites would be 3 and the original odly enough. I would include World, but I need to restart it one of these days since I don't have a definitive opinion on it. I agree with you on 3D Land, good but not Galaxy or 64 awesome.
