Walking simulators are a minimalist genre of games that lack many of the traditional aspects of gameplay such as a goal, win/lose conditions, or combat. Instead they focus on discovery and story through walking, exploration, and interaction with non-hazardous items in the environment. They sometimes feature puzzles, but these are infrequent or non-existent altogether and are never a key aspect of gameplay. Enemies or some other threat may be present, but "death" is rarely a risk to the player. Instead some other form of punishment, loss, or setback may be implemented.
