DH dms a regular D&D game with seasoned serious players once a week. They take it in turns to dm (6months - year at a time). They meet at a game shop (its one the guy who runs the shop arranged). If you are anywhere near a gaming shop - enquire, because a lot of them run nights. And theirs more and more internet games around using random number generators or skype.
Dh used to run a game for me and friends (who don't take it as seriously) but that stopped when I was ill/pregnant and needs to get up and running again but its finding time when we're all available 
Dh has done games for his (teenaged) cousin but they couldn't find enough people.
I really do enjoy it as a night with friends. I used to do food and we'd spend our time trying to drive dh insane as in 'so what would I need to piss in that nome's eye from 20 feet overhead?'. Dh also loves the creative side as he writes his own adventures/sagas but it does take quite a bit of time. He used to play with a guy who wrote his own rp world/system 
Dh is also into board gaming incl the D&D ones and other ones like pandemic, carcassonne, red november, chrononauts, flux (technically a card game) Ds is 7yo now and being playing some of these for a couple of years. A lot of them say for 12 years and up but there are quite a few kids of gamers who manage them fine from about 5yo. They're great for holidays and weekends. Ds can manage a full D&D game as long as its not more than 90mins/2hours but it needs more planning in advance so it rarely happens.
Dh had the computer programme thing for making monsters and player sheets/characters for D&D (we use 4thed anyway) but they relaunched it and it was shit so he had to redownload the original (cos it wiped out hs version) and no he can't get updates.
We've also got gamma world (D&D) but I don't like the feel of it.
I am a human avenger (I do like the new avenger class - its what I was trying to achieve with the ranger anyway and I'm not good enough to overpower it anyway, only level 5).
It took me a long time to get into rping because of a shit gm that made games essentially unplayable.
Dh's dice habit costs us a bit though not as much as his board game habit. We've got the new discworld game as a joint xmas present.
