It is one of the strangest aspects of play that whatever can be endured will ultimately serve to enhance the enjoyment of the player who perseveres. Tolerating repetition adds satisfaction to the completing task. Tolerating difficulty in challenges turns mere success into glowing victory. Tolerating frustratingly obscure puzzles leads to smug triumph when they are eventually cracked.
Of course, each of these ordeals to be endured will also exclude certain players from reaching their eventual rewards. Not everyone is willing to endure tedium, difficulty or obscurity. But it is striking to note that the same things which cause certain players to give up a game are the very things which make it worth playing for others. This is more than just ‘different strokes for different folks’ – it seems as if whatever a player will endure ultimately ends up enhancing the reward they experience.
