I played through a part of the massive, very well planned, very funny adventure map "241" with my minecraft buddy and we were shocked that Simon and Lewis didn't do this map. It's really entertaining and would be AAA material for the yogscast. I didn't find it suggested here. But there have to be other people thinking as I am and wishing for Lewis and Simon to do this fantastic map.

Here's the link, by the way. It's exactly the map that this Bizarre-Guy TRIED to do with the Trust Game and Teamwork Towers.
