I can get one game this weekend and I want it to be handheld becuase I'm going away in a couple weeks, and can't decide what I want more! Anybody wanna help me here?
I would go with Platinum. With that I am ensured classic, solid Pokemon gameplay. Retribution would be OK if the PSP had 2 analog sticks, but I'm afraid with only 1 shooters just don't work on the PSP
