awesome multiplayer game by any standard
I think both of those complaints are unfounded, as there is more content to come, and the maps that are there ellipse most other multiplayer games. Complaining about the single player not being as fun is like complaining that Counter-Strike sucking when you play with a bunch of Bots. Great game, worthy of a buy as it will be a multiplayer game that you will come back to again and again.. and again.
I cannot comment on the 360 version, but I imagine it is of similar quality., although, I couldn't imagine playing with a 360 controller, as this game requires fast, precision shooting in all directions. I could see the limits of the analog control making this game MUCH more difficult to complete
