Hmmm...a game that can let you do anything, and I mean anything.
A game that lets you be a flaming homo who kills conservative Christians, rapes their children, eats their pets, goes to a synagogue and kills every last Jew in there, then takes a crippled autistic child and beats him around, then cuts his limbs off and leaves him to die, then drives by the White House screaming racist slurs, then goes to India and kills and guts a cow right before a crowd, then gives copies of Common Sense to people in China, and then flash the soles of your feet to everyone in the Middle East, then Falcon Punch every pregnant woman you see in the stomach, and for the endgame, go to Africa dressed in a KKK robe, killing everyone you see.
That's all I can think of for now. Gotta love that huge runon sentence.
