My biggest "problem" when I first started playing sometime last year was I couldnt figure out how to do a charged attack.... ya know where you hold whatever button and then you do this badass attack when you release it? Well, my first version of pso was with PS-ZERO on the DS which hooked me upon seeing some of the awesome charge combos. At first I was saddened thby pso's lack of charged attack moves... but then I was sucked in by all of pso's other awesomeness.
