I would give a lot to charity. Like, the majority of it.
I would then build my own movie theater with one of the theater rooms in IMAX and another one with an actual theatre stage on it for local theatre companies. It would be set up like an older theatre with grand architecture, except with stadium seating. Of course, I would build a room onto my current home (or buy a new one) with a theater room in it as well, featuring a high-def projector and Dolby TrueHD surround sound.
The rest would go towards games, DVDs, etc, starting with paying off every game I would ever want for the next year.
I just gave myself everything I would ever want, including an ideal job to continue to get large sums of income from the community as well as helping the world out.
