Hell yes I do!! Got a lot of NES, SNES, complete in box, mint condition kinda shit. Also a lot of other game related novelty shit!

I also collect old Arcade games like NBA Jam and Mortal Kombat and shit like that.

I've been every now and then trying to get hold of PS1 classics, although without spending too much on them obviously. I've taken a step back from trying to buy them as it's Chrimbo time and I've had house things to spend money on however, I'm buying them because as a kid I couldn't afford them. My next targets are Rival Schools, Raystorm, Raycrisis and maybe the Discworld games.

I have a lot of GBA and Wii games, that's pretty much it :P
Although, the GBA boxes aren't in the best condition. I've recently started "refurbishing the boxes and making imitations of the missing pieces.

I did but most of the games i wanted were too rare or expensive so i gave up.
