Not counting the custom PC, I have a lot of gaming plushies: Rytlock, Amaterasu pillow pal and Chibiterasu keychain that I have on my tea thermos, PvZ sunflower and Mario characters, Raiho Kuzunoha and stuff. Lots of posters from video games and maps, too. Two video game tattoos, considering three more. SNES controller wallet and Superman Chuck Taylors. A Venom-themed bathrobe. Space Invaders themed messenger bag and a 200 dollar arcade stick to play fighting games from China. And two katanas, a three-section staff, and a pair of tonfa (still want to buy some nunchucks, a bastard sword, and a halberd).
God damn, now that I've listed that all out, that's pretty geeky. I never really thought it was much until I started looking around and tabulating it all, lol.
