of those games i see 3 that are system movers
blazeblu if they add anything and its not a direct port
uncharted in the west, no idea of the east appeal
and
disgaea 3, god know what a good touch control could bring to that game, and even if touch sucks, still one of the biggest time sink games ever, requireing about 20 hours for main story, another 1-200 hours to level characters
another 17 hours to level characters to max once you get the method set up
and another 19 hours to get the best weapons, minimum
and another 17 hours to effectivly level the wepons, and thats
and the 17-19 hours is a per character and item basis. with each character takeing up to 4 items and a possibility of 10 characters out, with i think 40-64 in storage i forget the exact number.
if you factor in that you can pause and suspend the psv like the psp, this could literally be THE game for on the go play.
