SORRY 4 ASKING AGAIN!!

Which one covers these topics (in 1,2,3 order) ((1 being MOST important))

1) Campaign mode (single or multiplayer)
2) Replay value
3) Multiplayer
4) Achievements (are they hard to get or easy)

So tell me which one you think wins each category.....

1: Left 4 Dead, it is the best game from those 3. It is fun, but it get's boring after a while. 2: Halo 3, i was a big Halo fan, got all the achievements but gets boring once you reach a 1000 EXP. 3: CoD 5 SUCKS!!!
