Two of the games included were Shock Wave and Guardian War, and it turns out they weren't the standard releases. I'm attaching a picture so you can see.
Both discs have a "DEMO DISC - NOT FOR RESALE" logo, but if you play them, they seem to be full versions. I think these are complementary copies of the games that were given to retailers to encourage them to stock the games. Both have a "Key Selling Points" and "To order, call" section on the included cards. Given that they're printed on cardpaper that includes holes for a binder, they could have been part of a whole book of these...

Anyone think these would be valuable to collectors in any way? I think they're kind of interesting, but I'm only a casual collector, so I might actually prefer fully boxed versions.
