Story was fine (Nothing that I haven't witnessed in movies etc). Can't say I hated it, can't say I loved it. Felt like CoD, BUT, with MUCH greater visual appearance and special effects. Shooting in the game; as per any other modern shooter out there. Voice actors were good, not Mass Effect or GTA (San Andreas & GTA IV) good.
Bottom line... If you're looking for a modern shooter with GREAT graphics and special effects and some awesome (now and then, cutscenes), and roughly about 6-8 hours of gameplay, then Battlefield 3 is for you.
