What would you do first?
Take a vacation
Pay off all my family's debts (mortgages, etc.)
buy a majority share of Nintendo
College. Car. Apartment.
I mean, think of how swanky an apartment you could get with $100,000,000.
Invest some of it in an account with decent interest.
Arrest a cop. :I
Save half of it and spend the rest on reviving Glitch and Swingin Ape Studios and donate some to the poor
