Ghostbusters?! Thanks for the heads up...I didn't see it listed in the New Arrivals.
The Battlefield game has beautiful graphics and the gameplay is pretty fun. The servers.. not so much.
I actually like games like Band of Bugs, but I did not buy it because I can't stand the weird voice acting in the game.
