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 $6.5M — a different platform, not this one.

Project Hospital

Become an ace doctor, an aspiring architect and a successful manager at the same time. Design your very own hospital, tweak every detail or use one of the predefined models and just jump to the doctor’s duty. Contract different insurance companies to gain access to patients with interesting medical conditions, perform examinations, laboratory tests and use various equipment to solve the diagnostic puzzles. Hospitalize your patients, perform surgery and more! Use a collection of various objects, materials and colors to make it truly yours or save your time and use one of many different prefabs. From hiring to specializations, from doctors to janitors, make sure everybody is doing a great job and finds satisfaction in their work. Help your doctors and walk them through the most complicated cases or just follow your favorite patients. There are a few different modes in Project Hospital: Tutorial levels will guide your through the basics of treating patients and running hospitals. Sandbox mode offers endless hours of content, building anything from small clinics to huge multi-storey hospitals, starting from scratch or in one of pre-built hospitals or clinics in case you want to jump straight into management. Run you own ambulance service and help handle events and emergencies. The campaign will put you in the shoes of a crisis manager trying to save a few hospitals in critical state. 6 challenge levels will test your skills and let you focus on the intricate details of individual specialized departments.
