Thank you so much for the interest! I hope you and your kids have a lot of fun!
You nailed it! Even that they're guidelines, not hard rules. We tried to break it up so the different types of rolls have an equal chance to be used, but don't want creativity to be squashed. So if your group happens to find a way to use Resources instead, like luring the beavers downriver so they can build their dam where it doesn't affect your water supply, that's great too. It'll ultimately be up to the GM to decide if it's a good replacement roll.
