Game Development Dictionary
The necessary route from start to finish in a game. Everything that must be done to complete a game is considered to be within the “critical path”. This holds especially true in linear games, where a player is forced to proceed along a specified path. Often the critical path is shown to the player with “primary objectives” or “main goals” of a level or the game as a whole. Other, smaller objectives or secondary goals that are not required to finish the game are considered “non-critical path”.
