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 $16.8K — a different platform, not this one.

Hollow Island

You play as an adventurer arriving to Hollow Island, but what you do next is up to you: Grow crops, harvest, cook food, brew and sell potions, expand your property, explore the island, fight monsters, dig for riches underground, build camps and hoard your treasures! Features: Farming, mining, building, fishing, brewing and crafting mechanics. An open world, allowing a variety of playstyles. Action RPG-elements allowing different fighting styles. Random generated dungeons. A unique, more than an hour long, soundtrack by Vindsvept. Over 60 unique enemies and bosses. Over 500 items. Starting and managing a settlement, with settlers and farm animals. 23 different regions to explore, all with their own dungeons and mines and challenges. This game focuses a lot on the joy of discovery and exploration. There will be very little hand-holding - you will instead have to learn through trial and error.
