I own a life-sized Pikachu doll. Still in good shape too.

Sometimes you need a jewish keyblade I guess. 

Anyway, for me I guess, uh... 
 
A promotional video (VHS) for pokemon back when it was just getting started in america.  

Nothing sticks out more than the next. 
 
A crazy expensive computers, lots of consoles, hundreds of games, etc. etc.

I own nothing that compares with the amount of win you guys have. The most nerdy thing I really have is probably my Forza Motorsport 3 Limited Collector's Edition. Nothing really amazing.

Someone photoshop that.

Nothing like that, but my 10 year old stack of game mags was getting out of control, and a bit embarrassing since I was so attached to them . I ended up throwing them all out.  Ah, I wish I would have saved a few issues of PSM. 

A bunch of gatchapons of Gainax anime girls. Stuffed in a small box though, it's weird when I have to take out something from that box... Sometimes the pieces fall apart so there's a lot of random limbs scattered about... in the box I have.
 
What I do have in my room is 2 Gloomy Bear plushies staring back at me from a top my two monitors. At night their dark empty eyes and their long and bloodied claws reflect upon the monitor lights. 
 
God damn, how did this change into something a bit horrifying... I got chills down my spine.

Replica Sting and Narsil from Lord of the Rings (modeled after the ones in the film obviously). 

That looks like a Jewblade.

The original box for a NES Action Set, I guess? 

A Jedi robe dressing gown, but its awesome. A plushie Gizmo that sits next to my TV, an 18 inch tall Raphael from TMNT toy with Sai, a Shaun of the dead action figure, all 3 assassins creed models (yes that's right i bought the black AND white editions so I had both of them!) and a 36" gold coloured GoW lancer replica that I thought was 36cm, that thing is a goddamn burden.

ok im sorry but a crappy looking jewish keyblade is either fucking horrible  or fucking awesome.....hmm

" That looks like a Jewblade. "

Honestly, this is hard for me to figure out because I am a manager of a comic store, and I have a lot of nerdy crap. I am guessing the nerdiest thing I own is the original Star Wars promotional material-including lobby cards, a letter, and a book about the movie-sent out by Fox before  Star Wars released (in the original mailing box).

Used to own a spider-man statue, guess it would ether be a lot of comic books or the evangelion special edition box set. Fuckin awesome key-blade by the way.

Oh man,  now i want a Jewish Keyblade even though im not Jewish.  Jewblade sounds way better though.
As for me i own pretty much no nerdy things, some Game posters  and a small Storm Trooper . However if i had the chance i would probably buy more things.

A Lord of the Rings ring and this girls bandana. (Her name is...Ren? I think. It came with the boxset...)

SPOILER WARNING: Click here to reveal hidden content.

A Dwight K. Schrute bobblehead, and some Office, Homestar Runner, Ask a Ninja, and Giant Bomb T-shirts. 

My grandparents gave me laserdisk player along with a lot of movies.

When I was about 14, I went over to my grandpa's friends house. My grandpa's friend had a full woodshop in his garage (He was retired and carpentry was his hobby.) Anyway, I slapped down some plans that I found on the internet, and in a few weeks I had a full sized OoT style Master Sword made of wood. It was amazing. Still got it, too, though the metal rod running down the center is loose...

The Master Chief cat helmet.

A Piplup plush, early-2000's video card boxes folded and tacked on my walls as geekass posters, not too much else.

As for me... Nothing. I don't buy things. I have the poster from Halo 3 that was on the back of the control scheme and the map from Oblivion up on my wall, but those won't be cool for another decade, at least. I'll post then.

A ninja turtle shirt. Of course, it's not an over the top in your face ninja turtle shirt. It's just four normal black and white turtles who happen to have colored headbands and weapons wrapped around their shells.

Around 30 of those Zoids Models you got to put together, about 25 full anime series on DVD, and all 28 Godzilla movies. 
 
EDIT:  Almost forgot my abundance of anime and Godzilla posters on my walls, as well as various stencils from Mario, Metroid, and Zelda games.

" I own about 300 Star Wars action figures. "

The Stars of David are a nice touch.

My magic: the gathering cards and warhammer dwarf army 
Also Watchmen action figures 

I have a Dwight Schrute bobblehead and that Key to the City thing from completing Grand Theft Auto IV.  Oh, and my Mashimaro alarm clock that I partially broke.

I got rid of most of my nerdy stuff when I was 14. Probably the nerdiest thing I have a Ninja Tips for Healthy Living poster.

I totally own one of the limited edition Keys to Liberty City that Rockstar gave out to everyone who 100%'d GTA:IV within the first two weeks, or whatever it was...  I still hate those god-damned pigeons!!! 

Autographed painting of Gambit by two of the cover artists for the series. One being Mike Choi, and I forget and cant't read the other. have it framed and brought it to university.

" @j_meyer_13: That's actually pretty damn cool. Maybe it will unlock DLC later. "

I have a full set of Stormtrooper armor.  And there is a relatively famous picture of me on the internet in it.  I was at a party and me and the girl were a bit drunk...
