I am working on acquiring a minimum of HuCard, Instruction Manual, and Jewel Case, but having the cardboard Retail Box is a bonus if I can get it as well.
I currently have none of the TurboGrafx CD games yet and no equipment to play said games, so I'm looking into getting a Japanese Duo-R to be able to play Japanese HuCards and all of the CD games as well, since I also don't have an adapter to be able to play Japanese HuCard games on my U.S. TurboGrafx-16.
Any thoughts on which games I should try to acquire next would be appreciated.
