First two people already named the list of games I can think at the top of my head ;~;
Legends of Dragoon, the story was nice, gameplay and battle system was kewwwl (LOLWTFCOUNTER, HIT O).
Panzer Dragoon Orta. I reaaaally want a sequel for this. I liked the story and graphics a lot, and the gameplay was very fun.
And Jet Set Radio Future. This HAS to have a sequel, I mean, you rollerblade around Tokyo, grinding up anything you can, and the best part, you can spray paint into the police.
