Simulation Games

Hello, I'm going to give you a general catigory of copyrighted materials that have lost their owners.
Wargame and simulation game materials. So many game companies have come and gone, their material was fun but now is inaccessable to most people.
I collect that sort of stuff, so I have many examples at home (I'm writing you from work) and I'd be happy to help you get a better understanding of the types of materials I'm talking about.
Stifled uses
