I think that when you are creating a game there should be a NO TRUCES option.
It makes sense: just about everything else has a box to click.
When I played the board game, if you made a truce....well it was considered unfair to gang up on anyone..
Truces can be a good thing or a bad thing, so I don't want them banned.
I want to see two boxes you can check: #1 Truces allowed. #2 No truces allowed.
