I didn't find any download links on the homepage, and I wonder if it is possible to download and play with MoGo Computer Program on a local computer.
I think the best way to find that out is contact one of the project members. They left their contacts on the page.
It can be downloaded at http://www.lri.fr/~gelly/MoGo_Download.htm
This still needs a client program. Personally, I use Drago.
