Which region has the most routes?

Question

Hoping it's Alola since I am doing a wonderlocke...

Answer 1

This is what you get if you just count the numbers in the numbered routes.
Hoenn: 34
Sinnoh: 30
Kanto: 28
Unova: 23
Kalos: 22
Johto: 20
Alola: 17
There goes your hopes.

If you have a slightly different definition of a route, then just tell me and I'll hide this answer.
