No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $2.9M — a different platform, not this one.

Airships: Conquer the Skies

In Airships: Conquer the Skies you'll need to use all of your creativity and skill to design and build fearsome airships and land vehicles to give you the edge in massive aerial battles. Construct your vehicles by piecing together a vast array of modules, choosing weapons, armour types, structures, equipment and resources in near endless configurations to allow you to prevail against even the toughest foes. The vehicles are highly detailed, teeming with sailors moving around performing their individual tasks to stay in the fight. Your choices of vehicle layouts are crucial, exploring the design space of different crafts and their matching tactics to make sure your fleet emerges victorious. Once your vehicles are ready for the fight, you’ll give high-level commands to your small fleet, swooping, soaring, ramming and boarding others to gain the upper hand in battle. Ships and terrain are fully destructible: they can catch fire, explode, break apart, and fall, so you’ll need to choose your tactics wisely. Face off against giant aerial kraken, fleshcracker mechs, huge venomous spiders, clockwork wasps, and more. Defeat them and reap the rewards. Play across three distinctly different modes: taking on (or creating your own) bespoke Missions; building a mighty empire in Conquest, or destroying your friends in Multiplayer matches online or via LAN.
