Don't get the Go; it sucks. The controls aren't changed and there's no dual analog. The screen is smaller. There's no UMD and you're forced to download EVERYTHING over the internet, which is, in my opinion, a hell of a lot more of a hassle than carrying around those obnoxious discs. Sure, it looks slick with the slide-up screen, but it's $100 more expensive than the previous model with practically no improvements.
Before the Monster Hunter obsessives and jRPG faggots take over the thread, I'd like to recommend Ace Combat X: Skies of Deception as one of your first games. The dogfighting is extremely satisfying, and it's one of those games where you'll have to enjoy multiple playthroughs of the story to unlock everything. I've never beaten it myself since I've only been able to play it on my cousin's PSP, but it's awesome.
