I haven't played the ported DS version of FF3 yet, but I loved the original (translated ROM). The fact that they introduced that to America is pretty awesome. Pretty much one of the best FFs to date. Fuck FFX/XII/XI.
On another note, despite a lot of hatred Unlimited Saga got, I think they were going in a good direction with that. I've always enjoyed the unique SaGa gameplay and environments, and I hope they do something else with it in the future. Unlimited used a lot of roleplaying elements that you just don't see in JRPGs (like any form of strategy OUTSIDE of repetitive combat). The battle system is a real turn-off, though. In some respects, the game can be overly complex, but if they used some of those elements more effectively, they'd have something very great on their hands.
