Hm. It's not that long ago, so it's easy to remember the details.
I played Left 4 Dead two months prior to my 18th birthday. Til that day, I had stayed completely faithful to myself and didn't play any games that were not designed for my age. My father got so angry with me, when he found out. Bad memories. Very bad. The game was fun though. However not that much fun, that it would justify our fight.
