How would you make a game with a $500 million budget?

[nomad]

I would try to make a game that merges two popular genres, endless game and match 3 puzzle...wait, no I meant MMO and FPS.
100 million to develop the game
50 million set aside to develop DLC
100 million for initial marketing cost
100 million for future marketing cost
100 million to setup and run servers for several years
50 million leftover cash to cover "miscellaneous" expenditure
Total = $500 million game
