I attend and participate in the renaissance festivals. And various comic con and cosplay events.

Total Geek/Nerd here.

Video Games, anime, D&D/Pathfinder, most things Sci-Fi/Fantasy-related, DC/Marvel comics/movies, Trekkie, Whovian. Also I'm a math/science teacher so that opens up a whole other level of nerd right there.

Trivial Pursuit, reading and readathons, and I grew up on a healthy diet of sci-fi and fantasy. During undergrad I used to host weekly Trivial Pursuit parties for several years, inviting over 5-7 people and playing for several hours. I'd provide some food, and my guests would bring food, not quite potluck, but enough that we were never stuck deciding between eating dinner and going to the Trivial Pursuit game night.
I read a lot of sci-fi and fantasy, especially epic fantasy with deep, complex world-building.
I have not owned a TV in many years, so I never really watched Enterprise when it came out, but I watched Star Trek, ST: Next Generation, Deep Space Nine, Voyager, and all the older Star Trek movies. I loved Babylon 5 (and had a brief fan-crush on Marcus-the episode where he dies was traumatic enough that I stopped watching that show for a few years when I hit that episode). I've seen most of the classic Doctor Who episodes, and all of the modern ones. I watched the original Battlestar Gallactica as a kid, and have rewatched the more recent Battlestar Gallactica series many times.

I debate, I organise and schedule discussions in a debate format. I get in touch with church leaders and ask them if they would like to discuss anything from evolution to morality to the existence of God. You would be surprised how confidently some of them accept. My point isn't to win the debate but to introduce the actual positions of atheists and scientists. Most of the time we have a Q&A with the audience, and the satisfaction I get from this is when someone who had been improperly informed on a subject like evolution, learns for the first time the actual position science takes. I often get someone saying "I'm not a monkey" I then take a minute to explain to them that science doesn't think their a monkey either. I tell them you're not a monkey you're a primate, and the name primate is given to us not to call us apes but as a classification designated by science to show commonalities with apes. So no you're not a silverback ape or a chimpanzee. Your classification is a human primate, and we share more in common with apes than we do any other species on the planet. Then I list off a dozen or so common traits ending with chromosomes. All their lives they've been fed misinformation, In many cases I'm introducing the most accurate representation of sciences position.

anime, video games, fantasy/science fiction

I'm into a lot of nerdy stuff, but I'm really into dungeons and dragons. That's probably the geekiest of it.

I enjoy just about all things sci-fi.

Board games, card games, sci-fi/fantasy (books, films, TV shows), anime, cosplay. I just attended my first (NOT last) Ren Faire. I need to get IN to Dragon Con yet. I've attended the parade, but not gone to the actual con yet. Oh, and I was recently invited to LARP.

Question: are escape rooms part of nerd culture do you think?

WOW, okay here we go, hold on. I love mmorpg (I am currently playing World of Warcraft, Star Wars the Old Republic, Star Trek Online and DC Universe Online), star trek, star wars, firefly, DC & Marvel comic books, TV, Movies. I also enjoy reading about the supernatural.

Animes and gaming

Lots of video games

I'm a big fan of board games. I like comic book movies...well just movies in general. Although, I have never gotten into comics that much. I'm game for just about anything.

I like D&D, though I don't have a gaming group. I also game on the computer. My current addiction is Neverwinter. I also love to read fantasy novels. R.A. Salvatore is my favorite author, so is Neil Gaiman.

Board games ("Euro" type)

Ah nerdy actives, this is my jam. I game (rift, batman, blackops ect), we do Ren fair most years (yes I period dress). Board games and cards games are always good. We play a lot of cards against humanity.

Board games. That's my thing. And no, let me stop you right there. I don't play monopoly. Because I loathe it. Here's a list of only 10 of, roughly 30 games I have in no order.

Fortress America
Fury of Dracula
Dead of Winter
Time Stories
Dread
The Resistance
Ikusa
Ghost Stories
T.I.M.E. Stories
Tragedy Looper

Single player RPGS, Sci-fi shows like stargate and star trek, Lots of action anime and maybe one day collecting figures.

ALL OF THEM!!!!!!!!!!!! 100% stoked to learn and experience new things, always interested in other people's views (so long as they aren't regurgitating something they heard somewhere before)

I love watching anime and shows like Supernatural, cosplaying, I sometimes play video games, but rarely since i don't have a computer right now. I also go to conventions. Also like Star Wars!

Lego/Mega Construx, sci-fi/action movies, videogames I can afford, a very small amount of anime, and cosplays on tiny budgets.

watching the NASA channel and reading Neil Gaiman and Douglas Adams?

I have a regular game group, meet once a week, also go see a lot of movies

Scifi movies - generally love them especially the current spate of Marvel superhero ones. Some video gaming. A fair amount of computer work building and designing websites, etc. I read A LOT - that's a nerdy thing to do nowadays, no?

I like sci fi movies. Some board games. Not into gaming really other than ipad games. Love the horror movies but not sure that falls under being nerdy, just bizarre.

I’m a nerd for.... old buses, trains and vehicles and will travel miles for exhibitions etc. Also Telegraph cryptic crosswords doing more than one a day which is now becoming difficult as I’m running out. Obsessed with QI and Have I Got News for You (tv programs).
