A friend looking over various mapping sites pointed out that VGMaps seemed to be largely platform games. To test that I took a small census that led to a larger census that led to a great big census. It's not perfect but it gives you an idea of the site make up. The -#- numbers are numbers of games mapped not numbers of maps.

I didn't count games that were credited to a .com because I didn't know if they were made by just one person, and I didn't count anything that wasn't an image, like video.
