Hmmm. I'm 36, been married for 12 years, and have a 10 year old son. I'm also a game, book, garden, movie...geek.
My sense of time has never been screwed up because of playing games. That just seems silly to me. hell, if anything, my gardening habit would be the culprit. You realize how much patience you need to be gardener? How much TIME has to go by before a plant really and truly becomes what you hoped it would be in the beginning? A lot.
There are so few instant gratification hobbies out there that to single out gaming is just...odd.
Movies take forever to make. Books can take forever to come out(Are you a Song of Ice and Fire fan?).
On and on...
