In the example where two players (A + C) are attacking B, I get that A+C attack as one unit and B attacks them as 1 unit. How is damage assessed to the A+C joint force?
As if it were one force, no preference given to a side.
What does "attach each other as normal" mean if neither one has the first strike? Is it up to a coin toss to who goes first?
No first strike, who goes first doesn't matter... both attack and damage is applied.
A question that I asked Russ yesterday that bears repeating here: If A attacks B and B attacks A on the same turn, where does the battle take place? Who's the defender? (guess this might be the same answer as to the previous question).
Each battle takes place in the destination territory. It is possible for Territory A to send ALL their units to B, and Territory B to send ALL their units to A in the same round and they simply swap places.
If we run low on money after building an inf for 3 turns, does it stall in production civ-style until we have the money or does it disappear?
Gone... you cannot go into debt.
Omitted questions/answers are being worked on, but wanted to get this out there.
