Considered by many to be a masterpiece of video game design, Dark Souls is an action-based fantasy role-playing game, and was developed by From Software and first published by Namco Bandai Games in 2011.
Dark Souls was so successful, in fact, that it created a succession of similar games, called ‘Souls-likes‘. Not many games can claim to have created a whole sub-genre on its own, but this game did.
