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 $31.6K — a different platform, not this one.

Dark Sky

After a mysterious force starts pulling spaceships out of the sky, death and destruction rain down on the frontier mining planet of Wolf Prime, littering its surface with wreckage, debris, and danger.  Take on the role of Squig, a Wolf Prime denizen and shipyard worker who, with the help of his friend Norton, gathers a team of survivors to embark on a journey that will uncover the mystery behind the sudden cataclysm. Do you have what it takes to save the planet from destruction?    Engage in party-based turn-based combat, plan out each turn to optimize character’s abilities and defeat powerful enemies.    Strategically position your team members on the battlefield, where your choice of characters can significantly impact your chances of success.    Outsmart enemies by moving around the grid, find or make cover, or stay open and get a better vantage on your opponent.    Play cards! Inflict noxious status effects on your enemies and set up party combos to eliminate them.     Customize your deck using the branching card upgrade system to unlock new strategies and synergies.    Craft new cards for your heroes with resources you collect during the campaign.    Tailor your character’s decks to work with each other, or make each character unique; the choice is yours.    Upgrade your cards to perfect your strategy and build unstoppable decks.     Wolf Prime is a magnet for species from all over the known galaxy, each of whom comes to the planet for their own reasons, and each of whom will play a part in the story.    Meet a vibrant array of characters. Their personalities range from stoic and solemn to buoyant and whimsical, but all are deeply committed to saving their adopted homeworld.    Learn about the various factions vying for power on Wolf Prime: the Outworld Collective, the Mining Guild, the government of Moros… and the Runshaka death cult, of course.    Get to know the backstories of individual characters through engaging dialogue and compelling cutscenes.     When the ships start crashing around you, survival mode kicks in. But falling wreckage isn’t your only problem.    Take on beasts, bots, and brigands determined to stop you from achieving your missions.    Delve into the lore of an extinct alien species and their age-old enemies.    Uncover the cause of the catastrophe and save Wolf Prime from annihilation.
