Yeah it is too expensive, but since normal CoD seems to be crashing for me with no particular reason (and even after I reinstalled) I am suck with CoD2...
Single Player felt just like normal CoD but that's not what I'm interested in anyway...
Multiplayer is somewhat better for me (although many wouldn't agree with me), it has much less lag, the net code is better optimized, and there are new good maps. The only thing that annoys me is trenchgun (

) an idiotic weapon, and sniper is a bit too strong...
And also the weapons, submachne guns and MP44 sound like they're from future and not WW2...
But I got used to it...
