Collector interest
Forgotten Worlds ranks among Capcom's earliest Mega Drive conversions and accompanies the console's early days in Japan, lending it pioneer status. Published by Sega, it adapts the arcade's unusual rotating aim shooter, a control scheme almost never reproduced on other home formats. Loose values stay modest, but factory sealed Japanese copies complete in box have become extremely scarce, which is where collector interest concentrates rather than on the readily found cartridge alone.
