After getting a new PS3 and subsequently the game now doesn't freeze I've decided to vote and say my piece.
Best fps on the PS3 for me....at least until I see Killzone 2. Scale of maps and intensity of battles is immense, add into that the destructible environments and it brings a whole new tactical slant to the game. For example, the other night I was on the defenders side...defending the gold crates from a very slick outfit, they had us pegged back most of the game and we kept them at bay for most too until the alarm went off that a charge had been set so someone had managed to sneak in. Instead of turning round and running thru the corridors most likely to be met with his machine gun fire I turned round, flicked grenade launcher on and took out the wall of the room he was hiding in.....promptly 3 of us took him out and defused the bomb. That's Bad Company.
You factor is sound and it completes the package for me, amazing. Thru a decent 5.1 setup the crack of gun fire around you, explosions...rumblings of tanks nearby wobbling your controller about. Oh and don't have your speakers too loud if you planning on firing in a room, they have done a really good job with accoustics.
Now if the known bugs regarding mics were sorted and there was a decent clan system this would get a 10 without hesitation, but as it stands it's a 9, because the rest of the game is so strong and IMO puts CoD4/5 in their places as it does everything they do (level ups/weapon unlocks/Trophies & in game badges) but bigger, badder and better.
At £18 now it is a bargain too, every fps fan should check it out.
