LOL, maybe tweakboy can finally buy it. He's been talking about it like it's the holy grail of gaming but just hasn't been able to come up with the money for the past 8 months.
Still, I think they should be dropping it lower if they really wanted sales.
I think it's mostly a great game although it's pretty pathetic how little IW supported the game with bug and cheat fixes and balance patches. I bought it on release for $60 and am happy with the purchase. Recently I started playing it again with a friend. Of all the games we had smooth gameplay in all but one or two matches, and one cheater (likely wallhack). So not perfect but very good overall.
The map packs are also on sale. I may pick one up depending if my buddy does. Not sure what is better but leaning towards the first one (Stimulus) since the classic maps Overgrown and Crash I prefer to Vacant and Strike.
