Honestly I love the fact that we know so little about the region. We've seen some landscapes, but we know nothing more, it gives us sooooo much to discover! They're revealing a lot of things about the gameplay, the pokemons, ... So it would be the least they could do to let us discover Alola on our own.
Serebii says the evolution depends on when in the day/night you make Rockruff evolves.
Guys, my mind is kind of confused right now. From what I read in this thread, people are saying "I love Rockruff's Midnight/Daytime form so I'm glad I'm picking Moon/Sun". I thought Rockruff's evolutions are different based on the time of the day, not based on the game you're playing '-' But I might be wrong. Any information regarding this?
