I did play this game or at least was exposed to it as a child. I went back recently and read the rules and tried to figure it out. I would love to have the rights to develop a new version with streamlined mechanics but I have heard people have tried it.
As for Vast? David hasn't played many board games and I doubt very many from the early 80s. I asked and he confirmed he hasn't played this one. It probably helped draw my eye to it though.
