What to do with my $100 000? I'm 20 years old?

If I were you, I would save it for a rainy day. Think about this: are my living conditions good enough that I can live comfortably. And comfortably doesn't mean a flat screen tv in every room, a hot tub, and 2 game rooms! Just think: Do I NEED a huge mansion, etc.
No one can know what the future will hold, or if your "gamer celebrity" career will last. If I were you, I would put about 70-75% of that into savings and use the rest to your leisure! Do this with every paycheck, that way you can have spending money, but don't go into debt without realizing you're spending all your money.
