Hrmmm, I haven- Oh crap! Wait a minute
I was playing WoW when I was weak (Like lvl 30) and it was a event time, and I went to do one of the quest
I forgot what event it was, and I was going to the place and I said to myself "This can't be THAT hard"
Yeah, I ran away like a little pansy.
Edit: Another thing that happened on WoW: I was still 30 or so, and I wanted to raid a enemy small city, so when I went to raid the starting Undead town, I nearly died 10 or so times, and I just hearthed back
And also I think I have had so many "OH SHIT" moments in ME1 and 2 I can't even count them but one thing in MW2:
"Alright time to be a Son of a ***** on Hardcore Ricochet SD and kill my teammates
*Knifes someone*
*Dies*
WIN"
