Well, I added up the probable hours... and I was horrified.
Since Morrowind was released, I estimate I've played well over 1 000 hours. If I continue the trend for Skyrim, accounting for its general... betterness than Morrowind, I'll likely break the 1 000 hour mark in the second year sometime, putting my total average well above 1 000 hours.
I just thought I should add that, I do have a social life, I don't sit in my basemant all day playing video games, and I do have other hobbies. I just stay up late, and there's nothing else really to do at 1 AM.
