The dynamics of games usually vary with the availability of play spaces and equipment. For example, when a large group uses the only basketball court in a neighborhood, the games exclude many children who want to play. The team that wins takes on challengers, rather than giving up the court to others, and those with less developed skills are not given concessions when it comes to participation. Taking turns is rare when there are more players than spaces. However, when there are many courts and only a few players, the goal is often to accommodate everyone's interests so that nobody leaves and forces the game to end. This is a major reason that the informal games of children in low-income areas with few facilities and resources are often different from the games played by children in higher-income areas where facilities are more plentiful and there is little or no competition for space.
