Yea, I am not a huge fan of most portable games, even most games on the PSP and DS dissappoint me, except sometimes you find a rare "gem", and on the iPhone, I found Crimson Gem Saga. This PSP port is actually a full blown RPG and not just some sort of quick thrown together iPhone app. It's actually a game that consists of many dozens of hours of old school gameplay.
