I've only survived Dark Souls because I read a guide.
In almost every Dark Souls character I make now, I use cheat engine to get items. (99 gwyn souls, anyone?)
I have yet to complete the "Thy Flesh Consumed" portion of DOOM.
I'm stuck in DOOM 3.
I look up r34 for almost every semi-attractive female character in games. (Gwynevere's amazing chest, anyone?)
I won Bad Rats in a raffle and never even installed it.
I got AI War: Fleet Command during a steam Christmas giveaway and never installed it.
I never completed the story in LA Noire
I Re-enact the Hatred trailer in GTA IV.
