A trope found mostly in role-playing games or adventure games, where the world's population consists almost solely in communities and towns throughout the world. The hero/party will visit all sorts of towns, ancient civilizations, futuristic/technological utopias, war-ridden dystopias, small towns, metropolises... but generally, there will either be only one form of entertainment or one city where entertainment can be found. Many times, this will be the largest town (but not always), but you can expect that whichever city this can be found, and whatever the form of entertainment is, you will at some point be forced plot-wise to take a part in it.
