This is a 20th Anniversary PC package. It comes with the 4 games (PC ports) shown on the box, plus a special edition mouse & mouse pad. The mouse itself is blue, with the 20th Anniversary logo, and the pad has the logo plus the "Sonic & Classic Sonic TV" art that Sega made for the event. It should be about $30 at "The Big W" store...which is pretty good for 4 games plus 2 anniversary exlcusive items. This is available in Fall 2011.
