As for my sins...
Whenever there is a character creator, I spend hours perfecting them. Skyrim and Mass Effect 2 probably have a good 2-3 hours spent tweaking character appearance alone.
As a kid I sold systems and all games from those systems to Gamestop to fund getting the next console. And I have re-bought a most of those systems/games in the past 10 years.
I played so much Skyrim that I actually got bad headaches and eye strain when I played or even watched TV at all.
Bought a PSP and almost 10 games for it. Have only played one of them to completion...and it was Little Big Planet which is about 3 hours long.
