Got Sun at launch, got past first totem thing and put it down as I didnt like the way it strayed from what I was used to. The year after i went and got Ultra Moon did the into and realised it was the same game. I plan on finishing at least one of them before S/V come out as im craving a mon game soon. Do I need to play the originals before ultra, like white before white 2 or is Ultra Moon just a better / updated game. Cheers in advance.
