So going back to forgotten worlds on the Sega CD from the PCE, it wouldn't be as good based upon what? Colors? What is the Sprite limit for the Sega CD, is it the Same as the Sega Genesis? Here are the Specs I could find, strange that the Sprite limit wouldn't be up'd in any way. The system appears to be a scaling power house however.
