For my first serious map, I decided to make the full Kanto region, based on the first generation of Pokemon games. I released it under the ZLIB License, because it only uses resources found in the official Sauerbraten release (please correct me if I'm wrong on the license).
I made a blog to document my progress more in-depth, which I listed as the project URL.
I welcome any comments or suggestions! If you would like to help work on the map or improve it, please contact me first, and I will give you more details. I prefer to continue using only the official Sauerbraten resources (objects, textures) to keep the map development as smooth and streamlined as possible.
Also, this is just a map. There will be no player interactions or Pokemon-styled gameplay, at least until I have the entire map completed, so please don't ask questions like "How are you going to catch Pokemon?" or "How are you going to implement the fight system?" because I'm not planning on doing any of those things.
I'm trying to make the map as close as I can to the original Pokemon maps, I am using the Kanto maps from the Red/Blue games on strategywiki as a source. Also, I'm trying my best to make it realistically scaled, so that if I ever want to make a SP map out of it I can.
I welcome feedback! Please just keep it helpful and constructive.
