I don't care for the newer games at all. I mainly play the PS1 Final Fantasies and a few other RPGs of that era. When it comes to newer games I like Gran Turismo 4 and I want Gran Turismo 5. FFXIII does not look good to me also FFXII seems kind of not for me as well. But anyways the games I play still and have replayed quite a bit are...

Final Fantasy IX (This game is my most loved game ever.)
Final Fantasy VIII (Replayed this way too much!)
Final Fantasy VII (Absolutely love this game.)
Final Fantasy VI (My second favorite FF game.)
Final Fantasy V (I just love it very good replay value.)
Final Fantasy IV (I have not played it in a long time and I don't have it anymore but I'm going to get it again. I really like this one.)
Chrono Cross (Probably one of my second favorite games behind FFIX.)
Legend of Dragoon (Awesome game! I love it it is tied with Chrono Cross for me.)
Gran Turismo 1,2,3 and 4 (These games are very fun it is a blast driving the Nurburgring with the G25 steering wheel in a Mazda RX7!)
