I just bought CoD last week, and man, what a blst. I was a bigtime MOHAA luver for a while b/c of the moddability, and all the different weaps that one could play with. Yet, CoD is WAY more indepth with the weaps, and I love how you can aim down the iron sights in the game. I just finished it last Monday (took about 12 hours), It's well worth the ride when you play it on Veteran or expert level. The deciding factor that made COD better than MOHAA for me was the fact that in most levels you have a strong sense of URGENCY to take a position, but you had to use a basic strategy in order to take. Reminds me of Boot Camp and Inf school:
When taking a machinegun nest, one member will crawl up underneath while the rest of the team lays down supressing fire. Then, the lone guys chucks a grenade in the hole. After that, it's gravy, the bad guys freak and run out or bumble around with the nade' and BOOM! Fun for all. I couldn't belive thought that those tacs really seemed to work for the most part in the game! I was really impressed with the entire thing, and I hope that some expansion comes out, or even a TC mod- which would be alot of fun! BTW checkout www.codfiles.com
