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 $26.2K — a different platform, not this one.

Illuminaria

A resource management game where you command a swarm of intelligent robots in a quest to save the world. Choose where to build, what resources to gather, and then watch the robots do the heavy lifting. They'll gather the resources, build, load weapons, fight, and respond to the world around them. Instead of having a sandbox world, you'll need to build several smaller bases with finite space. Be on the lookout as all the bases keep functioning at all times and can be attacked by the enemies. The game has five regions, each with new resources and technologies to discover. Vicious enemies of darkness will attack your base, attempting to destroy your reactors and steal your resources. Build turrets and load them up with ammunition to repel the attacks. Adventure and explore to find hidden treasures, and fight enemies in auto-battles. This way, you'll get rare resources to use to your advantage. Liberate the world by lighting beacons and crafting your own army The world of Illuminaria was taken over by darkness. Unravel the story about what happened on the planet as you clean and liberate the five regions by lighting beacons and sending your armies of golems to attack.
