My brother got the game and I'm playing it too, it's very entertaining. We've unlocked Roy, Riza, Scar, Mei, Gluttony, Armstrong, Izumi and Ran Fan so far. The game's so much more interesting as you get to play different characters, and as long as I ignore those annoying combination attacks, I get quite addicted. I'm wanting to play Bradley now but my favourites so far have to be Roy and Scar... although the Roy/Riza partnership is quite awesome, I have to say.
It's not bad for my first PSP game
