Buy the entire Mass Effect franchise and make my own trilogy of games that follow my vision. Also the games will be heavily biased towards a Tali romance.
Buy a decent house, a car, get into Uni, and put aside about $100'000 for the future. I've entertained the idea in my head various times, about starting up a workers cooperative if I ever had the opportunity to do it - so maybe I'd start up a few of them. The rest, and most of it would go to charity.
Buy my town you will have the best weather in the country with hot women and beach front property and the people here will give you a good old Californian welcome(Drugs and Hookers)
Buy my parents houses and tell them to stop working, get my music career started up, and oh, I don't fucking know, buy some weed?
Some weed... WHO HACKED SHAWS ACCOUNT! WE ALL KNOW HE WOULD BRIBE THE GOVERMENT TO LEGALIZE IT! Even me
Save enough so that those closest to me, my future children and myself would live comfortable lives, not overly extravagant but enough to never need to work again and have good healthcare and a decent education. Then I would spend absolutely everything else on charities and helping those in need. I am not sure what charities but I would certainly also donate a large sum to help with the research of certain diseases. Perhaps I would establish something to help those who were closely affected by suicide, say the family members of the victim and such.
I am so jealous of ComradeLer... huh never thought I would hear those words, never the less say them.
I'd buy the most bad-ass computer there ever will be. And only use it for FL Studio. Fuck videogames, I'd be happy with that. But, I suppose I could do other stuff with a billion Canadian dollars too...
