Haven't had a chance to play it yet. I'm not a huge CoD fan, but its a great way to keep in touch with some of my buddies who've spread out across the country. We play together with some frequency and we've been getting bored of the original maps. So, I'm hopeful that it'll give us a change of pace from the launch maps even if they aren't the best maps ever.
This is just my personal opinion, but the new maps are some of the worst in any CoD. Either the quality of maps is deteriorating, or I am now incapable of enjoying CoD. It's probably the latter since I've been playing it since Finest Hour. I'd like to see some completely new FPS games come out soon.
