The Rpg Maker series is great for making such a diverse game. I like this, it has a real community feel about it allowing people to be in the game etc.
The CBS looks pretty nice - the concept is great.
Maybe add 1-2 custom Pokémon which are really hard to catch/find ;)
Overall i'm glad to see this project is still alive as most Pokémon fan game makers quit half way through. You have a big following and no doubt it will continue to support you fully.
Good job.
P.s to Avatar referring to the post about not allowing him to use certain material. You are being harsh and the only thing you did was hinder the progress of a good project. This is the internet anything you post and make public will no doubt be ripped and circulated. And in the case of finding someone using your work why be so harsh about it? You could of simply said ''Hey I made them overworld sprites you can credit me for them or not use them." instead of the approach you took. :/ You should be supporting projects like this.
