Heh, I guess I list some geekiness I've done too then.
- I've played Warhammer and Warhammer 40k (aswell as lots of other GW games like Mordheim, Necromunda, Blood Bowl, etc.) since the 90's. I've got around 20-30k points of Fantasy and quite alot of 40k aswell. Had my own table with lots of homemade terrain, etc. before I moved.
- I've seen ~200 animes in all genres, from school-life romance to bloody samurai series, etc. I also have a fair collection of both anime dvds and manga books.
- I collect NES-games, I't isn't my prio one thing when it comes to money but I've got games like Final Fantasy, Mega Man 5, Duck Tales 2, etc. complete.
- I collect comic books. Mostly stuff like Tintin, Spirou, Lucky Luke.
- I've played LOTS of pen and paper RPGs, mostly Swedish games though.
- I collect model trains and have quite a large collection in my opinion. I also build my own model trains in both plastic and brass. Soldering and painting myself.
- I've played MtG since Tempest was released and have lots of cards like an all-foil madness deck. I've also played in nationals a couple of times.
- I was a big roller coaster geek a few years back, I also played Roller Coaster Tycoon on competetive level and finished in good places in some tourneys on the internet.
- Slackware Linux and OpenBSD are my favorite operations systems.
- My music collection is approaching 900 items.
- I played WoW pretty competetive and reached the end of AQ40 as a Warlock class leader.
- I'm a big Tolkien geek and have read pretty much every book about his world that has been released. When I went to school there was a Tolkien group there who always wanted me to join because I knew more about his works than pretty much every member of said group. x)
I can think of lots more stuff, I've tested lots of board, TCC, battle top games etc. but I can't remember everything.
On the other hand I really like beer, I party alot, don't look too geeky and am not a virgin so in that way I'm not a classic geek. :>
Edit: looking at the list I'm definitely a collection geek. I'm materialistic as fuck and LOVE to collect lots of different stuff.
