I think its a mixed bag. Some games go up and others down. I think some of the recent ports on next-gen systems have caused more people to experience the game and want the originals. For example, the virtual console on Wii and XBox live. Some folks want to experience the originals. Heck if I could afford them Id want some Metal Slugs, but I have to settle with the Playstation 2 MS Collection for now.
