I would invest about 1 million, but as soon as it doubled .. I would take out that million so that way ... I won't be risking any original money in case my investments ever crash.
I would most certainly give money to charity ... matter of fact I probably would go as far as to give a quarter of it to charity.
I would purchase a house ... nothing big .. just a normal decent sized home with a few extra rooms. I would furnish the house and deck it out to make it look amazing. I would purchase every single game system in existence and as many games as i can find for them to create a huge library of video games.
I would create a server room that has a NAS of about 1,000TB+. I would launch a game hosting service, web hosting service, and maybe even launch as a Youtube Network for gamers.
I would hire a bunch of elite programmers and artists to work on a VR MMORPG and start up my own game studio.
I am sure I would do a lot more with it as well XD.
