The Infinity Ward games are a lot easier to complete and can all be done offline (I was able to get 100% in CoD 2, 4, MW2, and MW3 with little difficulty).
Treyarch's achievements really piss me off though.
-Call of Duty 3: It'll take days to get General even when boosting, years if playing legitimately
-World at War: 10th prestige impossible b/c of modders; some Zombies cheevos are tough
-Black Ops: Zombie Easter Eggs only possible online and need dedicated players
-Black Ops 2: Not hard from what I've heard but still has lengthy multiplayer cheevos. --- "Guess what?! I got a fever, and the only prescription... is MORE COWBELL!!!"

Cool, so don't worry about Achievements and just play the game. Black Ops 2 has like 3 multiplayer Achievements that you will get very easily if you enjoy playing online. If you don't enjoy playing online, then don't !@#$%&* worry about them.
