Elon Musk spending simulator https://www.spend-elon-fortune.com/
My son introduced me this game yesterday. You have 200 billion to spend on various stuff. Fist I bought 100 of Abrams tanks, 12 islands, I wanted to buy a millon of my own Tesla cars, thought to be good business decision to buy all my production to further boost company value but every click increases only by 1 item so i was not able. It was only 1% of budget so I added another Abrams tanks to count to 200, well I did not know what else except some planes and helicopters and 2 or 3 Hollywood movies about me.
