Coffee Wars

You're the new strategy chief at Ember Coffee, one of only three big coffee chains in the country. In every town square your rivals Kova and Grindhouse answer every move you make. Cut your price and watch them copy you in a price war. Win shoppers with adverts, new drinks and better quality instead. See barriers to entry keep a newcomer out, and find out what happens when the big chains agree a secret deal to fix high prices. That's an oligopoly.
