Don't listen to Nikolopolis. Bridgecraft is a stinker. It's like a pre-school version of this with crappier physics. Cargo is better because it is challenging.
Excellent premise, poor follow through. The game is tedious and repetitive, but still worth a one time play through. I sense a great sequel or three...
