I am planning to make a Go client with Unity.
I want to make a Client that has good graphics, since all clients I know only have basic 2d graphics
Unity is free as long as its not used to generate money.
If anyone wants look a it https://github.com/Seikusa/3DGo
is the github Link.
At the moment it only consists of the basic structuer of the Unity Project.
The next milestone is having a usable go field to place stones on it.
Then I will need to provide with basic UI.
After that comes sgf support
Then when those basics work, I will try to emulate the KGS client site, which will most likely be the hardest part.
