"Complexity borne of the combination of simple things. Linearity in games can offer the benefits of structure and focus, but it comes with a loss in novelty after being experienced once. Linear games, while respectable in their own right, also tend to lack offerings for replayability. Many games nowadays include multiplayer to extend longevity, but that is only one solution to this problem. Creating scenarios and game mechanics where emergence can flourish is a seldom used alternative solution, and if it’s applied to single-player content it can still function independently of the accessibility of servers or the solvency of the game’s developers."
