I'm assuming you meant on your first playthrough, so I'm striking my recent replay-conquering of SotC, RE4, and SH2.
Indigo Prophecy was the most recent one (though I needed a rage-pause for the shitty, tacked-on stealth mission). Before that was Escape from Monkey Island which I beat out of necessity, since I skipped the check for free space on my memory card without realizing it and I didn't have any room for a save, lest I let the previous four hours go to waste.
I beat Ico at a party where I wasn't having too much fun, since my roommate's annoying boyfriend at the time was there pretending to relate/bond, so naturally I gave him the ol' "Hey, I'm going to be playing this game for the next six hours, hope you don't mind."
