Does the game end ?

When the battles are fought the game may end.

Usually this happens after a predefined number of strategic rounds, battles or just after a predefined amount of time.

You could also use a predefined number of stacks or total points as end condition or just play until everybody gets bored.

Designer notes.
We usually play 3 battles a day and at the end of the day we decide whether we play another set of rounds and battles 3 weeks later.
