A practice game? You mean one in the original game?
There's Edi's fixed version, which adds some nostarts.

Then there's llama's version, which I assume is based off of Edi's, but makes swathes of terrain less homogeneous. I must admit, I enjoyed Edi's version of Paraganos quie a lot, but am interested in hearing what people think of Lllama's version.
