Hardest 1000 You Completed

So alot of people will ask whats your last, favorite, etc.. game you unlocked the full 1000 gamerscore points on - Well I would like to change it up a little and ask what was the hardest 1000GS that you unlocked.

I think mine was Avatar: TLA: TBE (Just Joking Around) - Mine was Call of Duty 2 finished it the 3rd day I had it but I had the flu and it was super hard playing with a fever and just being sick.. but I could not stop until I completed it.

Sorry, one more, Family Game Night!!!
1400 ach points for me!!! The kids liked to play that one too!!!

i agree with eternal sonata but kingdom under fire was much harder

Either NFS: Undercover (last achievement was a pain!) or Assasin's Creed because of all the senseless collecting!

Hardest ~ F.E.A.R.
Longest ~ F.E.A.R. 2

probably lego batman and lego indiana jones! Only cuz it took so damn long!

I'd have to say Civilization Revolution. I haven't completed too many difficult games. Well, none really.

Completing Ninja Gaiden 2 (full 1250) is most definitely my hardest accomplishment. However, finishing Gears of War was the most time-consuming thing I've ever done. It took me 13,768 kills to unlock "Seriously...", not 10,000!
