Like some others, I'm picking the missing choice "quit my job and work fulltime on gamedev". It's not that I *couldn't* right now, but it wouldn't be financially responsible to make my wife the sole breadwinner. With $50mil, though, I'd do whatever I wanted. Actually, I'd probably start a consulting gig on the side, too, since I actually like that, except for the uncertainty of where my next project is coming from and if I'll like it. With no money worries, I could afford to only take interesting projects, gamedev or not.
