It's a great euro game with lots of interaction, only 6 actions to do, but very deep choices. You'll mainly build your engine through cards, but your position on the board and timing of the actions matter a lot slowing you a a viriety of strategies.
You do need to feed your workers, but, contrary to some reviews I watched, I didn't feel it was that hard and such a tight economy.
Highly recommend for euro mediu-heavy players.
