Looks like it would be to easy to stay such a perfect image. And because as you say its pretty limited.
I have my "I whit PWND N00b" shirt from VGcats. Halo 3 MC (logo from Halo 2 boxart) shirt. My "Halo 3 Beta tester" shirt. I have a bunch of others...can't remember right now...
I always wanted the one that had the pictures of the Zelda 1 and 2 weapons and said "Don't make me go Zelda on your ass" or something of the sort. That one was kick ass, but I've never seen it in a store.
I have a Nintendo Rehab Clinic Tshirt from about 5 years ago. I wear it all over the place even though the letters are cracked and the hem at the bottom is gone. But my wife just bought me a Wii one
