- Photography (Nature)

Mostly:

1) Reading
2) Listening to music
3) Watching movies
4) Role-playing games (player and game master)
5) Occasionally doings maths/stats (for some reason, it's a bit of a religion experience for me... some people read religious texts, I read math textbooks and do math problems)
6) Running (spring, summer, fall)
7) Swimming (late spring, summer)
8) Bicycling (spring, summer, fall)
9) Hiking
10) Going out with my gf

I watch anime.

And when I have a few minutes free between gaming and anime, I might open a scifi/fantasy book.

Reading, music, movies, old hardware collecting, biking, trying to achieve lucid dreaming....

Everyone should play basketball, it's the most exciting team sport \o/

That being said I've kinda lost interest and only playing once a week now hehe

Film-making, cycling, reading, swimming and travelling.

I am not quite sure what qualifies as a hobby, e.g. is watching TV and listening to radio a hobby? Maybe just list activities which you feel take some effort. So, just watching movies (from TV or video-on-demand) is not a hobby, while collecting DVD-movies and running a web forum about movies is. Sex possibly doesn't qualify either, it is the same as saying "eating" or "social drinking".

Besides (retro-)gaming:

- martial arts (two different at the moment, right now not doing it as much as I really should)

- gym, albeit there has been hiatus of many months now...

- swimming (once a week usually)

- downhill skiing, albeit this is quite rare nowadays

- skating/ice hockey, but again quite rare, I don't play in any team or anything

Shit, is that it? Mainly just some sports, not even team sports that much? Does visiting web forums like GOG qualify? I won't mention "travelling" either because I usually do that only once a year, if even that. And lately to the same part of the world every time, so it is a hobby as much as visiting my mother is.

I notice that I don't seem to have many "intellectual" hobbies like reading (I feel I don't have time for reading, maybe if I stopped gaming...), building rockets or anything. My work already gives me enough intellectual stress, oh yeah gaming does too sometimes. :)

I have certainly tried lots of things (shooting guns in a range etc.), but they don't count if I don't do them semi-regularly. Just when the mood strikes and I feel I need to shoot something.

And now my hobby list sounds quite "manly", even though I am much closer to a nerdy type. I just try to compensate for it with my hobbies.

UPDATE

-I watch a lot of films, I go to cinema pretty much every week. Sometimes more than once.
-Don't watch anime anymore, got bored of the same cliches and hate the direction anime is going in
-I still listen to a lot of music
-I don't read so many books anymore
-I read quite a few comics
-Made a short game recently
-Kind of bored of games as of late. Pretty much only playing multiplayer games.

If you're making a collection of different partners, then it counts. Probably also counts if you're combining photography.

The wife and I are slowly trying out handguns, to see if we may enjoy target shooting as a hobby. We don't currently own any firearms so it's limited to the virtual range for now. Sooo many different handgun options that it's a bit overwhelming at this point.

I'm trying to get more into motorcycling. Had the bike almost three years and I don't think it has 3,000 miles yet. Pretty sad.

A general interest in automotive stuff. My brother and I spend quite a bit of time on the weekends working on vehicles when the weather is decent.

We've also done a lot of work on his old house but a new business venture of his has taken away much of that time. He's the one with the construction background so I'm more of an educated go'fer and am becoming master of the sliding compound miter saw. He sees it as work but I enjoy the brother-bonding time.

I spend enough doing it that it must count as a hobby: thinking about what we want to do to the house. Not actually doing any of it, mind you, but perpetually making plans.

I'd like to get into amateur machine shop work but the cost of entry is a bit steep and I'm not sure where we'd find the space for the equipment. And not sure what I'd build. And my 2D vision makes welding pretty pointless.

Gardening might fit in there but it's more like simply pulling weeds.
