What are some of those single-players that were either SO difficult, challenging, or other wise over-the-top moments that upon completing gave you a great deal of satisfaction simply because you actually managed to?

Obviously MGS3. I desperately need a radar for MGS games.
I really want to say a Total War game, but the endings are sooo unsatisfactory given the amount of effort you put in. I think it's cos about 5 battles before you complete it you already know you're gonna win.

Castlevania.
Dear lord those games were difficult.
For me anyway.
Gears Of War and Ghost Recon Advanced Warfighter for some reason made me go ape when I finally finished them. But I think the RAAM fight was most awesome in Gears when I finally did that.
