3 is pretty damn hard to find, and it's really whatever.
I can attest to the difficulty of finding this game. It took me two weeks of Google searches and manually checking Gamestops all around New York City. I found a copy in a Gamestop at King's Highway all the way out in Brooklyn. It was the last copy and grand-spankin' new.
Got it last year and other than hating the hell out of Garrod's voice and the complete excuse of a plot, I'm still elated with this game and Amuro's awesomeness therein. The dialogue gets repetitive as fuck, but eh; beggars can't be choosers.
