Because I get some of the ad space as well.
You get the banner position, the preload ad that accompanies your game, a link back to your site, and a clickable logo.
PassPlus gets the attract mode rich media ad, the text on the “INFO” section of the menu, and the emails it collects from users.
I tried to construct this system so it gave everyone a fair deal, and I hope I’ve done that.
