Hard to pick one really. I loved cod 2. They should put Burgundy in a map pack
Cod 4 was awesome, at least it didn't have stupidly high killstreaks for rewards that just promoted camping. unchangeable 3-UAV, 5-Air Strike, 7- chopper. I enjoyed it loads. Especially when I got the Gold AK47:evil:
MW2 was great, loved playing it but it does get boring sometimes. Stupidly hard unlockables and massive camper enhancing killstreaks. I also think they got lazy putting together map packs for mw2 that contained half the maps from cod4 /facepalm
I voted mw2 since I actually enjoy playing it and it's good to get on there with mates and have a blast. Plus the fact I don't have cod2 or cod4 anymore.
