48 years old, married for just short of 25. My wife didn't play RPGs when we got married, and didn't start playing until her kids started getting serious about them. Go figure. She's never minded my playing, and never minded playing hostess when the game was at our house. In fact, having a non-player on hand to run drinks, cleanup, and munchies has been awfully nice. I think she's just glad I only watch football with my dad (who passed away shortly before our marriage) and my uncle (who is a 12 hour drive away, so it only happens rarely.)
She does play RPGs now, and enjoys playing Traveller more than anything else. Her name appears with mine and my daughters' in the Mongoose TMB. We'd been playing CT for some time before Mongoose announced their playtest. She was extremely annoyed that I suggested interrupting an ongoing campaign to playtest the new rules--she was the only player who voted against it. However, it was her reaction to the new rules that led to me running a largely Mongoose-rules campaign now.
How much I have played outside the house has largely depended on me and my connections with other players. I played more when I was younger and doing more SCA in an area where more of the SCA were gamers. That's had more of an effect on how much gaming I do than being married.
On my wife--she enjoys games and competition but has never really been into role playing until a few years ago. Though we never did RPGs together, we've regularly played a wide variety of board and card games together since out marriage.
As to career, yes. Since before I was married I've had both a "day job" and my own business. At different times of my life one or the other has dominated. Neither business has ever been gaming related, though at different times my work has put me in contact with either a new set of gamers, or gamers looking for a home that I've invited to my games. The worst for gaming is when my "day job" eats up my time, because my "midnight engineering" work is usually flexible enough to work around a gaming schedule.
Presently, my "day job" is part-time teaching, whereas my own business (engineering consultation) is my main job. So there's less conflict with my leisure time. Though it does happen. Fortunately, it usually happens about the same time my players start calling to say they won't be able to make it this week.
There are times when we're able to play often, I may run up to three games a week. More typically I'll run one game regularly once a week, and have a second campaign that meets about twice a month with a slightly different group of players or a subgroup. Which campaign is which will change back and forth.
The past four years my family have become my core players. Since we enjoy having others to break things up from it being "just us" we usually have at least 2-4 other people playing in a campaign. Just one other person feels a bit overwhelmed by themselves, over 4 starts to get to be too big a group to run without people getting restless while waiting on what others are doing.
Before that it was me with from 3 to 5 visitors, the girls would sit nearby and pretend to play their own campaign with each other, and my wife playing hostess.
Now I'm looking at how to keep gaming going when the girls move out. They've been my biggest source of out of the house players the past couple of years--friends, boyfriends, etc. Where's the old folks' home for gamers?
