Cool that (the E4 thing).Well, considering there are many different building styles, then that means Rainbowpolis will be a hard challenge for your spriting hand, Baro, good luck with that ;)
It'll be interesting to see what is inside of the clubs be careful XD.
By the looks of it, Rainbowpolis will be the place where a lot of stuff will happen, I guess the player will have to return to this place many times, right?
Oh, and about the player's room script, dont worry much about it, because when you defeat the E4 you start out outside of your house, in one of the warp events (in fact, you can specify which in the "Oak and Hall of Fame" event), but anyway, you are still somewhat far away :P
Don't worry about adult content on the clubs, you'll just battle bunny girls, maids and [caucasian] belly dancers. Baro'll be there in a gag (you get close to him, he spots you and flies away).
