There was actually some guy who wanted to build a gaming company but he was having hard time actually figuring out a way to get money for the development, it is insanely expensive to build a decent game, if you are a one man developer for the game it will take A LOT of manhours, like unimaginably long, hell 50+ developer teams actually take literally years to build a decent game, think how hard it is to do it all by yourself, only stardew valley comes to mind when talking about one person built games that became successful.

However that dude realized he could issue tokens, and use that funding to actually hire people and build games, then people who have those tokens could just give those tokens back and get the game in return, you can either get the game and sell the game, or you can sell the tokens, what the game is worth in dollars will depend on the price so the market.
