Do you collect gaming-related toys, comic books, shirts, posters, etc., and if so, what?

I have mostly Nintendo stuff, because it's relatively easy to find. A Yoshi t-shirt, a Pikachu t-shirt, and a bunch of plastic figures, mostly from fast food and cereal box campaigns from when I was a kid (and sometimes more recently). A lot of them are Pokemon, but there's some Mario (and even some Kirby-- Kirby needs more love, seriously). There's also a Pikachu plush from when I was a kid. He's tattered and worn, but I hope if I have kids, they'll love him like I did.

I have the Valve "Steam Powered Tales" book, the Chell tank top, Ellis' "Bull Shifters" t-shirt, and my Archimedes plush came yesterday. He's very cuddly and adorable. Outside of official stuff, I have a ton of L4D2, Portal 2, and TF2 pins, and a "Medics Do It From Behind" bag. Unfortunately, while HALOLZ updated their design, they don't have a new version of the bag, and the decal is ripping off (serves me right for living in a rainy state, I guess). I also have my Genuine Purity Fist redeeming card hanging up in my room. (Mm, Heavies...)

As for the want list, I'd really like the Alyx Vance hoodie, but I don't know if I'm willing to pay $44 for it, plus shipping. Maybe when the price goes down. I'm also considering buying my brother a plush for his birthday in a couple of months-- I'm torn between Chibiterasu and either Tanuki Mario or Bee Mario, because Okami, Super Mario 3D Land, and Super Mario Galaxy are among his favorite games. Any thoughts?
