I tried to play MW1 the other and had one bar consistently. No thanks, I'd rather not deal with that. I do think that MW1 is the better of the two games though, but even MW1 had its major flaws. MW2 does have more variety though, which I do enjoy a lot. In MW1, it is all about the M16, M4, AK-47, AKS-74U, P90, MP5, RPD, M40A3, M82A1. USP, M9 (with MP5), Desert Eagle, G3 (Hardcore), and the M21 (Hardcore). Perk 2 really broke down to Stopping Power, Juggernaut (counter M16 and snipers), and UAV Jammer (Hardcore or on a bad team). But even then, Stopping Power reins supreme, unless you are running an SMG. Anyways, my current go-to class when not playing S&D is ... H&K - Silenced UMP / Akimbo USP / Throwing Knife / Stun / Marathon / Lightweight / Commando / Painkiller
