Buy the license for Vampire: The Masquerade and make the best damn freaking vampire game there ever was. I don't care for the specifics, but ensure it can break-even at realistic sales targets. Cut out the flab such as quick time events and pre-rendered cutscenes, forget AAA graphics, just make it a damn first person rpg and make it work. I would take a special interest in the weapons, combat, and level design, giving it a fresh and intuitive feel. Each clan would have a distinctive style and powers, and ample opportunities to use them. Also, TIME TRAVEL.
I don't care about the fate of the company after the game is completed.
