The most stupidly hard game you have ever completed/not completed.

I cant finish Doom 3. I either get bored because nothing happens for so long, or a million things happen at once and it scares me. Doom 3 makes baby jesus cry

I can't do the last boss on GUN either, the one in the mine.

Ninja Gaiden on the XBox and the NES for that matter was rediculously difficult.

No matter how many times i tried, the one game i could never complete was BattleToads on the NES.
