Final Fantasy VIII.
I know it doesn't have the best mechanics or narrative of the Final Fantasy series, but it just hit me at a place and time in my life where it was exactly what I needed to experience right then. And every time I go back to it, I don't see the flaws that everyone is so quick to point out - I just see everything I love about it.
VIII was different. I think that is perceived as a flaw by some. It wasn't the world-spanning epic of VII, and it didn't have the nostalgic feel of IX.
