Video Games Are Often Hated On and this doesn't help in terms of your real $100, but I would point out that most of my (also millennial-age) friends who are entrepreneurial souls got their start in MMO (basically means people playing together) video games online where a vivid "marketplace" economy allowed your character to work in trades, sell goods, and make profits.
