Excuse me you play as a -hireling- pretty much? What a fantastic idea that gets interacted with so much by the other factions. That's such a novel and exciting concept.
Mechanics are simple and easy to understand, which let's the theory crafting of possible interactions really shine. If things were more complicated then their ability to be used by other factions gracefully and effectively would totally be lost.
I'm assuming they score points when they place a building? I feel like this might snowball really quick since their build action isn't impeded by much (like wood for the cats). I feel like once you're established, you can easily build for something like 10 points. Yikes!
Awesome concepts and great submission :)
