Pokemon Big Blue is a hack heavily influenced by Crystal Clear. It’s a reimagination of the Kanto region with a full Open-World format. That means, immediately after naming your character you’ll pick from 42 different starters and choose where you start.” All the wild battles, trainers, and gym leaders in this game are scaled to how many badges you have collected.

As you collect more badges, you’ll see higher level Pokemon in the wild and Pokemarts will even carry a larger selection of items for you to buy. Through your adventure, we hope that you will interact with all sorts of people and achieve personal growth. That is our biggest objective.
