You could compete with other companies producing cookies! I think it'd add a bit of a fun factor to the game.
Something along the lines of you have to get twice that company's CPS, but once you do you can buy them out and you'll gain all of their CPS. Really expensive, but also really helpful!
Maybe that could even be a way to get some types of cookies (like we couldn't do Oreo's since that's copyrighted, but you could buy out the "Shmoreo's" company and then you have the Shmoreo's.
