PC Gaming has been my hobby (as opposed to pastime) for 20 years. I still have my Commodore 64 and games, I still have my Amiga and Games, and I have over 500 PC games.

I am sure that's not every gamesas title, but it might not be every gamesas title I own either, but I bet it's the vast majority in either case! By the way, every one is in it's box, with manual, map, novella and anything else that came with the original (mostly) big-box game!
