i'm a fan of those old school computer RPG dungeon crawlers that let you transfer parties to the games sequel.
i have the Amiga version of Buck Rogers: countdown to doomsday and i know that its sequel, Matrex Cubed was never released on the Amiga but on the PC. if you complete the Amiga version is there a way to transfer your party information into a PC format and then transfer it into the sequel?
