Become venture capitalists who create companies (that you name from choosing an adjective card and a noun card for some fun concoctions!).
Whilst gaining shares in any companies that you create, you can go on to either secretly invest in or openly buy shares in opponents companies.
The winner is the player who earns the most money (gained either through their own companies or from shares in opponents companies)
