yea man, but what if u have MW1? It's awesome too! i like that you can 'cheat' a lot in the oldskool mode. There are some bugs in maps which u can use to get out of the map in oldskool mode, really fun to do! Sad enough the bugs are fixed in MW2 :(.
If anyone is interested in these 'cheats' just search on youtube: Bugs call of duty MW1 or Get out of map Call of duty MW1.
