Couldn't resist.
OT: Any achievement that you need to in multiplayer, because they're just a complete dick move as far as I'm concerned.
I'm happy to say that I've completed MW2 on Veteran and I got 1000G in Halo: Reach (and then they brought out new maps and achievements which made me think "fuck this"). I almost beat Halo 3 on Legendary, but some of the levels. Ugh...
The worst are the really half-arsed achievements along the longs of "Accomplish Tedious Task X 1,000 Times". Ugh...
