Fun, but the controls are kinda wonky, especially if you're coming over from GTA and are expecting the same sort of polish. Great voice acting. Engaging story. Glad I'm finally getting around to playing it.
Also bought Grand Theft Auto Liberty City Stories & Vice City Stories Bundle. I've already completed Liberty City Stories, but it was an absolute pain. Understandable as it's a PSP port, but f*ck. Anything more than 3 enemies on the screen at the same time and you're forced to hoof it out of the area because of a joke of an aiming system. Still, it's GTA and the story is pretty damn good. Cool final boss, too. Impressive for a handheld.
Haven't cracked into Vice City Stories yet, which I hear is tons better than LCS. God, I hope so.
