It's not that much... I know. I've considered projects like building high speed rails across a country (several billion at least) building my own race track (several billion again) or some of other projects that would be self sustaining within a minimum of 5-10 years. I'd try to build an empire.
well you would try to build empire

you don't want to hear about my plans to capture the whole world

I have about 50 plans every of them would take 20-50 years to sucseed

aren't I smart? I would be freaking old dude when those plans would be complited and then I would be able to concuer the world
