Exploring the world is an important aspect of many RPGs. Players will walk through, talking to non-player characters, picking up objects, and avoiding traps. Some games such as NetHack, Diablo, and the FATE series randomize the structure of individual levels, increasing the game’s variety and replayability. Role-playing games where players complete quests by exploring randomly generated dungeons and which include permadeath are called roguelikes, named after the 1980 video game Rogue.
The game’s story is often mapped onto exploration, where each chapter of the story is mapped onto a different location. Rpgs usually allow players to return to previously visited locations. Usually, there is nothing left to do there, although some locations change throughout the story and offer the player new things to do in response. Players must acquire enough power to overcome a major challenge in order to progress to the next area, and this structure can be compared to the boss characters at the end of levels in action games.
The player typically must complete a linear sequence of certain quests in order to reach the end of the game’s story, although quests in some games such as Arcanum or Geneforge can limit or enable certain choices later in the game. Many RPGs also often allow the player to seek out optional side-quests and character interactions. Quests of this sort can be found by talking to a non-player character, and there may be no penalty for abandoning or ignoring these quests other than a missed opportunity or reward. Quests may involve defeating one or many enemies, rescuing a non-player character, item fetch quests, or locational puzzles such as mysteriously locked doors.
