For about a month, me and three other people worked on a Kanto region recreation for Pixelmon. We have finished and it is now 100% complete, including interiors and puzzles such as Silph Co., Power Plant, Celadon Dept. Store, and a fully functional Safari Zone! Every gym is also setup and ready to take on, along with the Elite 4. We also added accurate Pokémon spawning in long grass in their designated locations according to Pokémon Fire Red.
The regions of Johto and Hoenn are also complete, along with Sinnoh soon to follow!
