At first I though Alola version of pokemon were just reskins of old critters, like shinies but with different shapes instead of just different colors.
To my surprise, some Alolas have different abilities and even different types. Alolan Ratata is Dark/Normal instead of just Normal type of the regular Ratata.
I guess this add some interesting possibilites and it's definitely better than just being a reskin.
Now excuse, I have some Nintendo Switch news to catch, and Overwatch patch notes to read…
