Does anyone one know, if we play the game with the minimum player count which is 5, how long would the game take?This depends on the player type.
Inexperienced players will take more time, but also might avoid trading risks. Let me tell you: if you are afraid to trade, you will not get enough points to purchase civilization advances (including defense for those nasty calamities).
Experienced players though, sometimes may take forever to calculate their movement or purchases. You could set a time limit there.
Two weeks ago we did the expert AST with 5 experienced players. We played the full 19 turns in 8 hours.
I expect inexperienced players to require 8 hours for a full (basic AST) game, provided you have read the rules, and have played the first game before.
9 players will go up to 10-12 players, regarding the above.
