Card game in which players purchase companies using sets that have various monetary denominations (the resource cards). Turning in a set with matching symbols is worth more than the face value of the cards, so set collecting becomes a key strategy. Purchased companies (the corporation cards) are placed in front of the player according to a matching letter system. The top company of each stack is vulnerable to proxy take-overs by other players, so they usually attempt to order their holdings such that the most valuable ones are covered by less valuable companies. Scoring occurs whenever a player draws a profit card from the deck. The game ends when the corporation deck is exhausted.
