INTJ for people who care about that kind of stuff.
I do a bit of modding on the side. I've worked with several source mod groups in the past, mostly in level design.
I build custom computers, arcade cabinets, odd speaker/radios, Nixie clocks, and pinball machines on the side.
I'm also a competitive gamer. I've competed in several large tournaments. Not enough to quit my day job but I love competition of the mind.
Own a few Kayaks, do some reef and spring diving, and brew some of my own mead on the side.
Tell me my eyes are like sapphires.
Some of my favorite books are The Moon is a Harsh Mistress, 1984, Starship Troopers, Fahrenheit 451, No Truce with Kings, A Stranger in a Strange Land, Tiger! Tiger! (aka The Stars Are My Destination), Brave New World, and again I could go on.
I enjoy Ska, Punk, Big band, Folk music, anything that's just odd or different.
I have one rule with food. So long as it still isn't kicking by the time it reaches my plate, I'll try anything once.
I also enjoy games of all sorts. Board games, Table Top games, Card games like Magic the Gathering, and more traditional card games like Poker.
Favorite Video games would be Arena shooters like Quake, Tribes, Team Fortress 2, Natural Selection, Dirty Bomb. Also enjoy RPG's but more in the spirit of Baulder's Gate then Skyrim, and anything that tries to do things differently, or with a lot of hidden depth.
Something worth the effort
