Will the S4 style of this series ever come back? It was (still is) such a great version. I just do not get the same great taste from the later version of the game (5th and 6th). I think by taking the detail out of the economics theory of the game was not a bright idea. BB should improve on S4 concept and move the story to next level with more details such as addition of more elements into the tree of ecenomical progress. ( and maybe some hero class into this mix).

I had the 4th edition and played while ago. But now I don't have that copy anymore, I think it is lost(. Can someone tell me where I can get the S4 Gold Edition digital version?
