Collector interest
Forgotten Worlds ranks among Capcom's earliest Genesis conversions and belongs to the console's 1989 North American launch wave, 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 copies drawn from that first launch stock have become extremely scarce, which is where collector interest concentrates rather than on the readily found cartridge alone.
