have gone for ultra sun having purchased moon last year so thanks for letting me know. Did so before seeing your post but am happy i did it that way.
this game shouldnt exist btw
The "ultra" games are like an updated version of the same game, so Moon and Ultra Moon are very similar. It makes more sense to get Moon and Ultra Sun (which is what I have), as you will get a much wider range of pokemon to catch for yourself. I will also mention that the story in each is very similar, so you will probably feel like you are playing the same game twice (with a few changes).
thanks for that- appreciate the info
From what i can understand its the type of pokemon that you want to catch plus sun is based on real day time. Moon puts 12 hours on to what ever time you playing so its based at night time thats all i really know as i want to get in to it ready for pokemon go coming out on switch and the next game dropping next year. Only really got my 2ds a week ago becuase i dont like taking my switch outside my house plus i want something to play in my lunch times at work.
