Cooperative multiplayer video games may also have campaigns where players assist each other with a series of challenges or goals.
[5] In open world video games, campaigns usually consist of a series of linked quests that require players to travel to specific locations to continue the story.
Players who dislike being forced to travel and complete specific quests may ignore the main story.
Heavily scripted video games that force players to progress linearly through the story may be called "on rails".
For instance, White Wolf uses the word Chronicle for its World of Darkness and Exalted games.
