Okay, so I have 5 kids and I'm going to play the 4 player skirmish map with them tonight. Here's the modifications I'm making.
1) Girl's team: 3 teams of 30 points each. A 10, 9, and 7 year old.
2) Boy's team: 2 teams of 40 points each. Me, a 5 year old, and the two year old rolls the dice.
3) First team to 60 points wins.
4) No command cards.
5) Instead of losing cards with strain (you can still choose to take damage), you get strain tokens which do something. Suggestions? They slow you down unless you burn an action to get rid of all the strain?
