Detailed Description

The game event manager loads the scenario configuration object, and ensures that events are handled according to the scenario configuration for its lifetime.

Thus, a manager object should be created when a scenario is played, and destroyed at the end of the scenario. If a second manager object is created before destroying the previous one, the game will crash with an assertion failure.
