I had an unfortunate fail a couple of days ago...
I was playing Mercenaries and decided to make a new profile with the crazy Swedish guy. Only, the previous save was on the top, and I had gotten in the habit of just hitting the save and overwrite one time, so I accidentally overwrote my almost finished profile. So I have to start all over again, every collectible, every stat. But hey, that's where the cheats come in.
Also, my dad laughed at me...
