Mission: Quite Easy
We need to sneak in to a guarded house in the middle of town. It makes sense to wait until night to do so, which means we have to be quiet. We sneak closer to the house, but how do we avoid the guards? Which way are we approaching from? 'Do you want to put yourselves on the map?' says the GM.
Yes, yes we do. We place our miniatures on the map, inside the house. 'Well, that was easy.'
