No, not those. The OTHER versions.
Square Enix revealed that not only is Dragon Quest XI S: The Game’s Name is Too Long coming to Nintendo’s Switch on September 27, but the original trilogy of games, Dragon Quests I-III, will arrive that day as well. It’s worth noting that these aren’t the original versions of the game, or the SNES version (or other older iterations), but the more modern versions that popped up on PS4 and 3DS with, uh, questionable monster art.
Each game arrives individually, and will be playable in both Japanese and English. So, because the games haven’t been announced for the West yet, you might be able to play them if you have a Japanese account.
