Just noticed that there's an option to add the optional cards when starting a new game on ACTS. Haven't had a chance to see if that includes the Ames remix (although that just needs an agreement between players) or if they include the errata, but it's a good step regardless.
How do you suggest new optional cards? I was thinking of a card like "Juche" ("Remove all Soviet and USA influence From North Korea. North Korea is protected from realignment and coups.") to represent North Korea isolationism during the Cold War.
