Been trying to get into Sun/Moon (especially with Ultra having been released last month), but for some reason I just can't. The last region I was able to fully immerse myself in was Kalos, which is kind of disappointing since that was over 4 yrs ago. Time to wait for Gen VIII, I suppose.
Grab a Switch - next one will def not be on 3DS any more. Pick up BOTW while you're at it!
