We had so much fun playing this game (with my 8yo son, playing two characters each), with did the whole campaign twice just to make different choices the second time. The app is great with music and voice actors. I definitely recommand for families looking for an approachable narrative board game . Some rules details/specifications might be a bit unclear but I recommand you just make those decisions for yourself and enjoy the story with your kid!
This expansion is a lot of fun, and the extra tiles add to the fun factor that is Clank Catacombs. There are a few extra rules to keep track of, but they don't get in the way, and once you've played a couple times it becomes second nature.
