Well I'll testify to what Shlep0311 said...and add that "This game is a favorite hands down". When I picked this game up from the store on release day I was ecstatic but calmed down enough to get about a quarter way finished with the intense campaign but finally let myself indulge into the online multi-player and I was instantly an addict! The reason I haven't played it in quite awhile is due to the fact that the cd got broke when my friend ended up borrowing n it got broke when his 360 broke (after about a month of begging me for it I gave in and let him borrow it). Within 9 days or so he's getting a replacement for me so I might get back addicted to it. The enticing part to me was the new inclusion of being able to use vehicles online multi-player. Previously in CoD2 you couldn't and it ended up being just sniper matches from all across the map from all corners so it bummed me out but while I played the new addition of the vehicles totally stops this possibility. Next there's the classes you can choose from (example;Sniper,Destruction,light/heavy infantry). Personally I don't have any second thoughts about putting that money down for the game because it's like a never-ending party! Well thats my opinion but if you have played any previous CoD games you're sure to love this one so at least go rent it before buying just to make sure.
