Games like defender's quest

GOG.com (formerly Good Old Games) is a digital distribution platform for video games and films. It is operated by GOG Sp. z o.o., a wholly owned subsidiary of CD Projekt based in Warsaw, Poland. GOG.com delivers DRM-free video games through its digital platform for Microsoft Windows, OS X and Linux. In March 2012, it began selling more recent titles such as Alan Wake, Assassin's Creed and the Metro Redux series, among many others.

Poland, where CD Projekt and Good Old Games were founded, had previously been under Communist rule but in 1990, the old government had fallen in favor of a more democratic government which spurred economic growth. While under Communism, copyright laws in Poland were virtually non-existent and unenforceable, and copyright infringement, in the form of piracy by stripping out any digital rights management (DRM), was rampant across electronic media. The consumer perception of copyright in Poland remained the same after the change of government, making it difficult for legitimate sales of electronic media; pirated and bootlegged versions were sold in open markets next to boxed copies of the legitimate productions for a fraction of the cost.
