Expansion packs and mods and user created mods add to replay value, Black ops should of been an Expansion back to COD MW. This Worked well for BF2. And UT99-2004 Till Cliffy-B decided to become a pussy. More People Still Play uT99-2004 and the Quake series. Now what Im waiting for is another Borderlands- I had so much effin fun playin that game.
