I think on a forum that is targeted to fans of Final Fantasy, the general population would sway on the side of a Japanese RPG. Then again, I could be wrong; I'm new here and don't know anyone.

The two are very different games (I do have both). I probably prefer Dragon Quest, mainly because it's longer and has varied sidequests with real rewards that add to the gameplay. Overall, it is a superior game from a veteran RPG maker (I guess there is a reason it's the #1 series in Japan, even above Final Fantasy). The old school turn based system is kinda tired, but not gamebreaking.

Jade Empire is probably the best RPG on the Xbox. Not really saying much, but it's good. Too easy though, and short. I would prefer a well thought out action combat system over a normal turn based system. Jade Empire's combat didn't really 'click' with me, but it's a step in a good direction.

Overall, Dragon Quest is the superior game, almost unfair to have Jade Empire compared to it.
