Movies, games, songs are replayed to death by those that favour them, and the better the quality of the content the more replayed they will be by a larger group of people. Games are exceptionally dependent on this factor. If, for example, Smash Bros was good to play one round and boring to play any further it would not have the fanbase it currently maintains and Nintendo would have given up on it long ago. The worst pieces of entertainment are rarely if ever remade, but best often is.
