Since I got confused about platform availability for each game, I made a sheet with a detailed table about that. - eviltoast
Dragon Quest platform availability
docs.google.com
Main series Name,Original release date,Platforms PC-9801,NES,MSX,MSX2,SNES,PlayStation,Satellaview,Game Boy Color,PlayStation 2,BREW,DoJa,Nintendo DS,Wii,iPhone,Android,iPad,Nintendo 3DS,Wii U Dragon Quest,1986-05-27,Yes*,Yes,Yes*,Yes*,Yes*,No,Yes*,Yes,No,No,Yes*,No,Yes (1)*,Yes,Yes,Yes,Yes*,Yes...

If anything is wrong, tell me please.

I have made that table with help of MobyGames and Wikipedia.

You can also put comments in the sheet if needed.
