Single player

From Wikia Gaming

Single Player refers to a game, or a mode in a game, that is meant to be played alone, or are only able to support one player at a time. This does not refer to hot seat multiplayer, even though only one person at a time is playing. Nearly all games have a Single Player mode, some more focused than others. Games such as RPGs and Action games tend to have strong Single Player experiences with few, if any, multiplayer focus.
