I don't know if you played the PS3 version(s) of the game, but would you care to give some general impressions? I loved the NG series (don't intend to play 3), and occasionally get the urge to push some nostalgia buttons in portable form.
Don't wanna be left sour, though... is it worth it?
If you like the others you'll probably like this from what I hear. One big issue I've been having is accidentally entering first person view by bumping the touch screen while using the sticks. Sucks that they don't let you turn off the front touch controls completely.
