I'm dying for one on the GBA. Enough with the ports already. I still have my SNES with Mario All Stars, Mario World and Yoshi's Island so they're useless to me.
It really comes down to whether you want to play their first party games. For me, that's more than enough, as Nintendo's games are the reason I'm still a gamer. If they're games aren't your bag, there's not much in the third party exclusive deparment. Mainly Resident Evil and some games here...
It got a 6.5, 6.5, 6.5 from the three reviewers in EGM. The main gripe that was consistent through all 3 reviews was that the AI sucks. Rather than being smart and using cover like in Halo and other more recent FPS's, they are simply "complete dead eye dicks" was how they phrased it...
