I think Beta 1 should go from leaving the water city, then thru route 1 (im thinking about not having route numbers but rather names i.e: east meadow) then the pre-gym event, defeating the leader and also passing the test in the forest north of grass city.
Concepts:
Water city, the biggest populated city of the mirco-region with 100 people (golden rod has 70), and to the south have a second map which is like a port/beach area which connects water city with the sea route.
East Meadow, is a grass maze styled area, which is very long (about 100 X 25 tiles) with a bed and breakfast in the middle (healing cost $700, also has fresh water for sale), with lots of grass and slightly gruelling path.
Grass City, is a Eco-friendly city (solar pannels and mulch bins?) with lots of green, the gym leader(dr. weedle) also works in a natural medicine lab(which sells the bitter objects but later on has new products like: Green Potion, heals 90hp and is made of old potion bottles and soft berries.) The gym is very eco friendly and has 3 trainers, who use a mixture of grass n bug pokemon.
haunted forest is a maze like forest with fog and purple trees, it has lots of warp panels put there by its inhabitants of a cult of psyic trainers and shrine women. getting thru the maze and warp pannels there is the leader of the cult who gives u cut for making it thru.
