I don't understand why they won't release the source code. The server and client are .Net so it took me all of 20 seconds to decompile them but it sure would be nice if they released the source code so I could have their comments and a complete, working, solution file.
I understand it's old code but there are some really interesting things that I would like to learn how to do; like how they run the code for each bug vs. a standard game loop.
P.S. I used the excellent, and free, Reflectorby Lutz Roeder to decompile.
