I'd pay off my entire immediate family's debt firstly. Then I would speak to a lawyer and accountant to protect myself and my family. Then, based on the accountants advice, I'd set it up so my parents can live where they want to live or travel somewhere and renovate their entire house where they can live and no longer have to work anymore. I'd get my sister a house wherever she wants and no matter the size. I'd get myself a secluded house where I can live on peace and a car so I can work in peace and all the moochers can leave me alone. If also invest in starting my own creative studio where I'd be working on my own game and hiring artists, voice actors, musicians, and programmers that I know. And, since all that wouldn't use the entirety of the 100 million, I'd also use a good chunk of the money to help all those affected by the canadian wildfires because that just sucks what happened to those people and they don't deserve it.
