I was tempted to say "Super Mario Galaxy", but it needs to stand the test of time. It will take a few years to see if my opinion holds, and isn't temporary.

No series has produced as many classics and high-quality titles as the Final Fantasy series, and my favorite game from that series, thus, my favorite game of all time, would be Final Fantasy IX, the best out of the FF "Golden Age" (Which is the PS1 era, for any of you casual or younger gamers.)

Undeniably a great game. FFVII comes close, followed by FFVIII (A game that was, unfortunately, greatly disliked. For silly reasons, at that.)
