We, the pokemon3d.net staff, has from now (2016-09-02) discontinued work on this project and handed it over to a group of volunteers on Github. The project will be open source, and you can help develop it from now on. Check out the repo here.
"Why?" you might ask. We have unfortunatly lost interest in continuing development on Pokémon 3D. Also Nintento of America Inc. sent a DMCA takedown notice to Gamejolt (where this game was hosted) and asked them to remove all games related to Nintendo's work. Read the full DMCA here.
But you can still download the latest version of the game here!
Could Pokémon3D become a MMO?
The long answer: This game is designed for single player and coop play with up to 3 other players (a total of 4 per game). It will not be a persistent world. However, that does not mean players will be limited to only battling, chatting and trading with people in the same coop game as them.
All multiplayer features are heavily under development and not finalized, but one thing is certain, this will not be a MMO.
