what is the difference between the xbox game's name call of duty 1, 2 and 3?

Question

which one is the best?

Answer 1

all of them are awesome, i would get them all, or rent them if you're only going to play the single player mode. If you're playing the multplayer one, then buy them.

Difference is jusst different people and different events. But pretty much the same, shoot, kill, blow up things, etc.
