Sign me up! Coded Arms is the game that made me want a PSP (well, the previews anyway). I'm a big FPS fan, I even played the GBA version of Duke Nukem (which was painful) because I love shooting things so much!
On the topic of the control scheme, I would like to see FPS games that were designed for the PS1 before the dual analog came out, remade. That way the controls feel upgraded to the single analog stick, instead of downgraded.
Such as a remake of Jumping Flash (am I the only one who liked those games?)
