Hardest 360 achievement

[miracleboy]

Saw an easiest thread and searched for a hardest thread without success, so...

From my reply in another thread...

Host 1000 multiplayer matches in GRAW (1 or 2 I can't remember).

I think it should be hardest you have achieved, rather then hardest to get - as some are near impossible.. i.e rank #1 in world ones

Can be both if you like, but I was interested in the most difficult to get overall also. Those number one in the worlds are madness!
