The way to get rich quick is to be offensive and just let your game have free press as people freak and bitch about how offensive your game is.
All we need now is a game called "1963" about lynching fags, niggers, women and jews and that game will sell like a motherfucker. Make it as offensive as possible, make it as mean as possible, make it as crude as possible, yet make it look good... and the press will just roll in like fucking nukes.
Offensive is the way to go.
