As stated in the Cabinet forum, the version of most use to us would be CoG: EE (Crown of Glory: Emperor's Edition). It is the second release of the series & the one currently supported by Matrix. Not that we should add both, why not. But CoG: EE is what most are playing in the series.
http://www.matrixgames.com/forums/tt.asp?forumid=630Battles are still resolved by the A/I in the MP game.
File play is much more refined than the original and all turns can be played once by every player. Then the last nation (Spain) merges all the turns & executes it, then sends the file out. It is a much simpler process.
The game is quite diverse, in the economic, trade, diplomacy & war aspects, but offers a refreshing change to the HPS systems. I think one of the games the ACWGC uses is by the same company who made CoG.
The game will need for a seperate scoring system too. I'll dig up the iNWC's a bit later. Because the game ranks the final score based one 1st through 8th place I believe. It might need a little fine tuning, but I think it is worth it. We added in HistWar as a seperate system and to be honest, we had scoring systems at the iNWC for the three types of games. If all games can fit that model we are all set for future games just like these. All three systems were equally fair too. I'll piece together an example for everyone....remember, long CoG games can go for 6 months to a year or so....
On the final note I told the Cabinet is....I had mentioned to the group who were members at the iNWC that I am trying to get them a home here. So I hope they will all elect to join if we approve it....
It is really is a great game....
