I would make games that are controversial, IE, games where you aren't a space marine mowing down legions of aliens or zombies, or an Allied one-man army mowing down an army of Nazis/Japs without remorse. I would make a game wherein the main character is a Jew that must stealth his way out of a concentration camp in Nazi Germany. He wouldn't know that much about how to fire guns, so the kick-back from the guns would be a major pain in the ass if he decides to pick up the guns. He would have to bandage his wounds in a similar fashion to the main character from Farcry2. Everyone would speak German and would have subtitles complacent with the language of the country that the person bought the game in. It would be one of the few first-person shooters where you can see your body when you look down.
