Lets brainstorm concepts for interesting game themes. I'll start with a short list:
Scoop - reporters try to outwit each other to move up in the ranks
Tip - wait staff try to keep their patrons fed and satisfied
Evolve - creatures compete with another and evolve to a higher life form
Magnate - outwit others to gain control of key shipping lines
Mogul - outmanuever the competition and become a real estate tycoon
Express - carry packages and mail through the Old West
Outlast - survive longest during an invasion of massive proportions
Dive - dive for hidden treasure while avoiding pirates and dangerous creatures
Triple Crown - bet on your favorite horses and build your fortune
Hive - build the biggest, most prolific bee hive. compete for access to the best blossoms and produce the best honey
Flow - connect a series of pipes to ship resources from A to B
Race - compete with others in a race for mayor. cut deals, campaign, and kiss babies to win.
