This is how I see it in my head...
Guy One: Hey dude, I've got this great idea for a game.
Guy Two: Sweet... can I help in development?
Guy Three: You guys making a game? I wanna help.
Guy Two : Lets sell and actually make some profit of this game?'
Guy Three :Thats a great idea
Guy One :But we a need a company too.
And thats how Guy One, Guy Two, and Guy Three, became badass game designers and lived the rest of there lives as upper class citizen.
