Video Game Genre
Video games are categorised not according to their visual or narrative differences, but on their game-play interaction. Thus, a video game genre is defined by a set of game-play obstacles, which are independent of their setting or game-world content.
RPG Action game
This sets video games apart from books or films. Each video game contains challenges to overcome, and all games under a certain category basically have similar challenges. Still, video game genres are subject to change the same with the games themselves because some constants or criteria could become obsolete or inadequate. Hence, gamers must consider each game as under more than one genre.
