Like many people, I've been gaming from the Atari days onward. With that, I've built up a huge collection of games. I still have all my games from Atari, NES, Sega Master System, Genesis, SNES, PS1, PS2, and Gamecube. I'm actually going to start looking at how much it's worth.
I have had to move 5 times in the past 10 years. Unfortunately, it seems like my video game collection gets smaller and smaller after each move, perhaps because I get into purges of getting rid of stuff for the sake of not having to move it again. That being said, I still have a small collection of games for the PS2, XBOX 360, PC, and Gameboy Color. I have kept all of the games that I am willing to play over and over again, and over time have sold or given away games that I am unlikely to replay.
