"...and suddenly doubting that you remembered to “save and quit” when you last played Halo."
Really...? People fear that they didn't save the last checkpoint? No level in any of the X360 Halos is longer than ~30 minutes if you don't die regularly. Replaying a level from start shouldn't be a struggle at all. Especially since you should know the way the second time around and be able to quickly catch up.
OT: I'd say playing through Hardcore mode on Dead Space 2 was the scariest gaming related moment this generation. Not because the game was scary, but because the Xbox could freeze at any time while you were only able to save your progress at three selected points throughout the game. At one point I even completed over half the game with all three save files intact only to find the Xbox freezing. Needless to say the following attempts to complete this mode were terrifying.
