I guess I should introduce myself as well. I'm Sean (the Irish spelling for Shaun/Shawn). I'm 23 year old programming student, ex-wannabe-art teacher. I live in Europe, more specifically Ireland.
I've been playing games since I can remember, the first being Sonic 2 on the Master System, first game I completed being Castle of Illusion on the Mega Drive, first game I mastered being Might Morphin Power Rangers The Movie on the Mega Drive.
I went from casual gamer to a full on nerd when I first played Ocarina of Time + Abes Odyssey (my favorite game of all time). I have been keeping games since then, keeping the ones I like, and selling the ones I don't. I've been collecting PS1, N64, and everything after since they first came out. I used to collect for the Mega Drive also, but during a move I had all my Mega Drive games stolen.

I recently started to collect for 8 bit and 16 bit games. I have only been collecting NES, SNES, and Mega Drive for the past 8 - 9 months, with the vast majority of my stolen Mega Drive games back in my collection.

For Nintendo I collect for NES, SNES, N64, Gamecube, Wii, WiiU, GB, GBC, GBA, DS, 3DS. For Sony I collect for PS1, PS2, PS3, PSP. For Sega I only collect for Mega Drive games, though I will, no doubt, start collecting games for the Master System and Dreamcast eventually. I also collect for Xbox, Xbox 360. I do collect the odd game for PC, but for me personally, the console gaming experience will always overshadow PC gaming.
