Crusader Kings II
GTA has nothing on this
If you want a truly twisted game that makes you question what lengths you're willing to go to fulfill your objectives....don't get a GTA game. Get CK2. This incest-laden, murder-ridden, and war-filled game is perfect for you deviants out there who love killing your older stuttering dwarf son in favor of your younger attractive genius one. Or maybe you want to imprison your son and daughter-in-law who want you dead and then take your daughter-in-law as your concubine while you leave your cuckolded son in prison to wallow in despair. Whatever your sick fantasies are, just know one thing: you are not alone.
