Markstrat
Markstrat is a simulation game, created by Jean-Claude Larréché, that lets the players take control of a virtual corporation; making decisions on its behalf. Jean-Claude Larréché and Professor Hubert Gatignon developed the simulation from 1974 to 1977. After the game was developed it was distributed on an ad-hoc basis by INSEAD. The game is widely known, and played in over 500 academic institutions, including 8 of the top 10 international business schools and 25 of the top 30 in the US. The players of the simulation have to make number of decisions, in marketing, finance, research and development areas, in order to achieve a better performance than the competing players who also take control of a company.
