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 $141.3K — a different platform, not this one.

Rogue Trooper

Rogue Trooper is a futuristic tactical action game, based on the character from 2000 AD. Nu Earth is a hostile, polluted planet that is being torn apart by an endless war between the Norts and Southers. Rogue is a genetic infantryman (G.I.), one of an elite squad of biologically-engineered clone troops, created as the Southers' secret weapon. During his very first mission, Rogue witnesses the betrayal and massacre of his entire squad. As the sole survivor, he goes AWOL, determined to hunt down the traitor who sent his brothers-in-arms to their deaths. Truly freeform gameplay allows you to choose from multiple routes and tactics. Employ a ruthless combination of stealth and all-out action in wide, open environments. Use the unique upgradeable abilities of your bio-chipped equipment to strategically outwit your foes.
