Final Fantasy VIII. I was on and off like 4 times. First I stopped playing after the giant spider because it was too hard when I was 10. Then I played it again when I was 14. I got to the end, and I couldn't beat it because I didn't have good enough magic. I realized this when I was 15, and I finally beat it. I started it again to show my friend, and now I am at the end again, with all the good magic and the best weapons, but I haven't gotten around to actually beating it again yet.
Final Fantasy XII. It was just bad.
I started Final Fantasy VII, and I just got out of Midgar, but I haven't played it since.
So yeah, alot of Final Fantasy games.
