Are there any legal issues with using people's photos on the paper money? Especially the baby-meme on the $500 bill...
I also would love if you went more into your playtesting process.
I don't think so - it falls under parody/fair use and those are derivative sketches. If someone's going to really complain then I'll change it for production.
It is all about cryptocurrencies lately, so why not having a board game! Cool! :)
Looks interesting, but why Kickstarter?
Well, it's not cheap to produce and I can't see it being a huge seller in a bigbox store.
But why Kickstarter instead of an ICO?
I think an IBO (Initial Board Offering) would be more fitting.
