Most of my NeoGeo AES (11 on 15) and all my NeoGeo CD collection (23) are japanese, its so cheaper compare to NA prices. Also have few import on Dreamcast, PSP, DS, GBA and from Europe I got Xenoblade Chronicles special edition with the red controller.
I own some Japanese consoles; NeoGeo AES, NeoGeo CD top loader and a Wonderswan Color Final Fantasy II edition.
Im actually thinking to buy a japanese Saturn and few games, there are so inexpensive compare to NA.
