Well aside from gaming, I have a few other hobbies.
- I write poety, have a leftover of a book i once started too never finished that.
- I Collect Warhammer 40k miniatures.
- I listen to music
- Im also member of a shooting club
- I read books, anything thats interesting. Currently reading a military roman (for the dutch: Frank van Wezel's roemruchte jaren)

I'm planning on trying to make a game.
I know, I know, my non-gaming hobby is still related to video games.

What a surprise, I love singing too. Took up singing lessons for about a month, but realised my finances were too insufficient to support my interest. So I'm a bathroom singer for now. Once college starts, I plan to join a singing interest group
Other than that, I enjoy outdoor activities. I haven't tried many yet, but someday I'd like to do mountain climbing, skydiving and water skiing. I'd like to spend a week living for thrills. Currently, the only sports I do are running and hitting the gym (hence the fandom for the big barbarian Conan). I feel uncomfortable all over if I don't do something vigorous at least twice a week.
I also enjoy doing some simple game modding every now and then, especially in graphics.
Then of course there's some nightlife. Not a lot, but occasionally, I'd like to have a drink with friends and go explore the rest of this shithole island I live on. Surprisingly, it's more fun to travel at night than during the day.

- I've seen around 1.500 movies and got around 100 DVDs, so I guess I'm a big movies fan.
- I have a pretty big comic/manga collection, including series like Akira, Monster, Sin City, Usagi Yojimbo and many others.
- I also like football (some of you call it soccer) and I'm a Real Madrid supporter.
- Last but not least, I like books. From Terry Pratchet to Michael Moore, if it's interesting and funny, I like it.

My main non-gaming hobby is audio engineering, i.e. recording and mixing music. I try to do a couple of projects a year for musicians. Am planning to make a second career out of it.
Also, other aspects of audio. I like speakers, headphones, headphone amps, etc.
I like non-video games. Played table top RPG's for a long time, just starting to get back into it. My old gaming group from many years ago is playing again. Also enjoy pinball; have a full size pinball machine.
Read a bit, listen to lots of music, write computer programs as day job and sometimes as a hobby, try to get some sunshine in the summer. Snowboard a little bit in the winter, but not terribly good at it.
Race cars, solo 2 autocross.

I game.
When I don't, I cry.

While I watch a lot of movies both rental and owned (owning over 300 DVDs minimum -- no way am I actually digging them all out to count them right now). I wouldn't say that was a hobby so much. As I pretty much usually have a movie on in the background while doing anything at the PC (including while working)
I don't really have much free time at all for gaming let alone anything else =/ so while I'd like to say I also spend time reading the many books I have (but have to read) or using the art supplies I have to draw (but have yet to even open), I can't.
So basically, if I'm not alseep, not working, not coding or doing other website related tasks, then I'm either attempting to play a game, procrastinating or dealing with the horrors that are two young children.
So at a stretch, my hobby is spending money on things I'd love to spend time using, but not ever managing to. Hell, I even have several DVDs that I've owned for several years and not had the time to watch! 72 hour days in a 12 day week would be grand.

I dabble in a number of activities
I'm a lead singer and bass player of a 3-person folk group
I read a lot, and pretty much whatever I can get my hands on.
I write. I'm going to school to be a journalist, with the hopes that perhaps I will write a book someday.
I talk about how much I hate my home town in illustrious, writer-like prose.
I hang out on the GOG boards

Do you have anything you can show us? I would love to hear this.

I really enjoy climbing trees, which is where half my username comes from
Aside from that, I spend most of my time outside work doing capeoira or gymnastics. I also do rock climbing and parkour.

Except games I like making model kits and, until recent, having fun with R/C Modells. Great fun I must say...

When I'm not gaming I usually like to pop in a good movie and relax. I used to read more than I gamed but lately the ratio shifted, though I promised I would rectify that starting with Shutter Island (that book has sat there unread for too long). I also enjoy writing but haven't found the time/motivation to do much of that either. So anyway I'm just going to blame GOG for cutting into my hobbies...

Form a GOG band but in the spirit of things you can only play retro sounding music

Like King Crimson retro?? Just how far back are we talking about??
