Dungeon Keeper was originally released in 1997 by the legendary Bullfrog Studios, the same company behind classics such as Populous, Powermonger, Margic Carpet, Theme Hospital and Syndicate. It's a dungeon management game where you play the dungeon keeper, digging out new rooms, giving homes to monsters and setting up puzzles and traps to defeat the invading heroes. It's still one of the (relatively) few games where you play the bad guy. Dungeon Keeper 2, released in 1999, retained much of the same classic gameplay but moved the series into full 3D graphics.
Both games were originally released for Windows 95, but GoG have tweaked them both to work - relatively - stress-free on modern systems. They are both absolutely brilliant, so frankly going to get them for nothing (or almost) is a no-brainer.
Electronic Arts recently caused huge controversy by releasing a mobile/F2P version of Dungeon Keeper for tablets and phones that was absolutely terrible, forcing the player to spend significant amounts of real-world cash to progress anywhere. GoG's move means that people can instead sample the original, superb games for nothing (or almost).
