The only Call of Duty campaign to give any amount of gravity about what you did was COD4. The ending was wonderfully pessimistic.
I wouldn't call what they did to Left 4 Dead 2 "slight changes". They absolutely butchered that game (no pun intended).
lol I had hours of fun vs the crap multiplayer bots of Medal of Honor: Rising Sun. Who needs good AI when crap AI is so much more entertaining.
