I'm hopefully moving to Japan next year for about a year. My fantasy is to go collector mode (I don't know how feasible it'll be financially) for the main series Gen I and II games, including the three Stadium games.
>Super Famicom
>Super Game Boy 2
>Link Cable
>Japanese N64
>Stadium, Stadium 2, and Stadium GS
>Transfer Pak
>Red, Green, Blue, and Pikachu
>Gold, Silver, and Crystal (internal battery would be an issue)
>Pocket Pikachu 2
>Mobile Adapter GB (probably lacks any sort of functionality)
At least handhelds and controllers are region-free, so I might be able to use my own.
But it would be cool to treat the Stadium series as my endgame content.
