I have a suggestion which meets a lot of your criteria, but the problem is, as far as I know, it's PSP only.

You'll find it as either Kingdom of Paradise or Key of Heaven depending on where you are in the world - if you can access a PSP then have a look at the review on here. It's an action RPG with absolutely fantastic graphics for a handheld system. Definitely worth trying.

Probably a good idea to let everyone know what you currently like to play - it would definitely affect what I would recommend to you - e.g. if you love strategy games, then RPGs that have a tactical element to combat are more likely to appeal, whereas if you love running around killing everything in sight, in an FPS, you'd be better starting with Action RPGs.
