First let me mention that there is now a way to check on the status of game starts.

when all 5 demo nations are filled, the game starts.
Now to answer the questions:
At the moment I have only 2-player blitz games (posted in another thread) or 5-player demo games.
Under consideration are:
A)3-player demo games with a couple of AI's thrown in
B)MegaChallenge games that will start when all of the nations of that era are filled, there would be 3 of those
For later consideration:
C)MegaArmageddon game where all of one era gets filled by players and all of the other nation slots are put in as AIs (that comes to 79 total)
D) Chaos games where each province is filled with additional random armies
E) Ally-for-Survival which would have random armies added all over the map, and all 79 nations, and the AIs are randomly allied with each other while being set to impossible setting. I suspect this would be a game where humans allied to each other would be a necessity rather than an option
