The dining business in Dallas is big money—and if you think you have the chops to be restaurateur, try your hand at Restaurant City. This game lets create your own virtual restaurant, down to designing a menu and picking the décor. If you upload the game to your Facebook account, you can also hire your friends. You loose points, for things like overflowing toilets or unhappy customers. No doubt, this one has some long-term productivity-killing potential.
