After reading about Collector's work being used without recognition, I wonder if some of the sellers are doing the same and using installers created by the community or mashing user patches together and creating installers.
Example user: allvideo. What annoys me about this user is that they list games using box images of higher value editions than what is actually being sold (like in the case of Sierra games, they list with the main image of the earlier and more complete collections while selling the cheaper VU collections). I get excited when I see those collector's boxes and then realize it's just another allvideo auction.
