I spoke to Fencer a while a go about single & multi-player games.
He has them on his list but wanted to make sure BK 2.0 was fully stable before for starting on something else major (as we all know there are still bugs about).
He did also mention the need still for a better server as there would be more players here at the same time, if they did not have a normal game to play they would be playing solitaire games.
I love the idea and think it would be an asset to the site, as the players would still be within BrainKing, which can only be a good thing.

*think someone could take 'Outbreak' off GT lol* :-)
