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 $10.4M — a different platform, not this one.
The Escapists
Includes the Free DLC "Santa's Sweatshop" The Escapists provides players the opportunity of experiencing a light-hearted insight into everyday prison life with the main objective being that of escaping! Players will have to keep in line and juggle their time sensibly as they form their personal plan of escape; working out potential routes to use as well as being incredibly smart and clever in using what seem like harmless items to craft and create various weaponry and escape tools which help aid the player in their ultimate goal of escaping. Players are tasked with advancing their character's statistics through various means such as exercising regularly and ensuring to boost their intellect as well… Whilst remembering to attend roll call, hold down their job and keep the inmates on side if you're to be successful in trading with them and ultimately… Don't forget to escape! 8 Fully operational prisons complete with routines to give you a flavour of how it *really* is inside! 10 Separate job opportunities for you to sink your teeth into… If you have the knowledge to earn and hold down these employment paths of course! 188 + Unique Items for you to seek out and perhaps even craft useful items with. (Team17 fully endorse the use of various weapons such as ‘shivs’, ‘nunchucks’ and ‘maces’ – within a fictional setting of course!). Various Favour types for you to tackle offered up by inmates – You wouldn’t want to go upsetting them now, would you? Highly opinionated and incredibly funny inmates and guards to keep you on your toes as well as providing entertainment! Multiple escape routes for you to work out and achieve the title of ‘The Escapist’! Multiple save slots so you can have more than one escape attempt on the go!
