Routes vs Wild Areas

- route = yellow brick road effect, if you stray too far the Poke you run into are bigger, stronger, higher levels & require late game badges to control

- inbetween routes are trees & super tall grass, some rivers bu they have "strong rapids" which take a harness and/or strong poke to cross (to prevent easy travel until you've earned it)

- SOS battles (contained to wild area)

- dens in the wild area where older, generally more aggressive pokemon spawn
