At 53 I'm older than most but younger than some, a nice middle of the road place to be. My wife of 33 years is not a gamer but she does watch the whole My Space, Facebook, etc. world where our children reside and keeps us both informed as to what is happening in their world.
My son is a big-time World of Warcraft player. So much so that we have to threaten him occasionally to keep him in the general vicinity of reality. He is getting better now that he has finally gotten a girlfriend that's worth having. He's 19 and on summer break from his 1st year at college.
My daughter likes to play Downhill Domination and ... the dancing one ... having a senior moment and too lazy to look it up. She is 18 and still trying to decide what her life is going to be about.
First computer game was playing the old Star Trek, ascii-text thriller on a college main frame back in the 70's. Favorite quarter-eater? Gosh! Too many choices. Sucked at most of them anyway so it really doesn't matter. My bride and I spent many an hour in the arcade during our later childhood/early marriage years. (Do the math. I was 20 and she was 17 - just kids) Also, played a lot of the SPI board games during the 70's. Just couldn't get enough of the hex maps and cardboard counters. PanzerGruppe Guderian probably being one of my favorites, although I did play a lot of Outreach as well.
Currently, I play GalCivII:DL and Victoria a lot. I own a ton of games and have that cursed habit of hording games I know I'll never play again, like the DOS versions of High Command and Third Reich; but that's why I bought a house ... to store my "stuff".
Currently looking to get a bigger house.
Playing time right now is very random due to real life concerns, like house-hunting and shopping for a pickup truck to replace my worn-out Escort wagon. I usually manage to get at least 6 hours a week of play under my belt. Usually more than that, but at least that many.
TBS is my favorite game-style due to worn out reflexes and poor eye-hand coordination, and the fact that I find RTS and shooters to be rather repetitively boring.
Most played computer game was Stars! I played it single-player and PBEM for years before I finally moved on. I was thoroughly thrilled with I finally discovered GalCiv last year.
