How are we handling Famicom Disk System (FDS) games? Do we treat them as NES games or as a separate system? As an example, Metroid (http://www.vgchartz.com/game/6343/metroid/?region=All) was originally released in Japan on the FDS (http://www.vgchartz.com/game/44164/metroid-fds/?region=All). It never received an NES/Famicom release in Japan.
I think we should change the Metroid FDS console to FDS (instead of NES), link it to the Metroid NES page as an additional version, and remove the Japanese release date from the Metroid NES page (since it was never released in cartridge form on the NES/FC).
