9. Fable 3
Fable is a series well-known for its odd sense of humor and fantasy adventure motif, but it also makes a great multiplayer experience. Exploring the word of Albion is made so much more fulfilling with the one you love by your side. Fable 3 is the story of a prince or princess who has been forced out of the Kingdom by their evil brother. The player then has to start a revolution, overthrowing their brother and restoring good to the land. There are numerous side quests and mini games to change up the pace of the game. The story is generally light-hearted, almost to a fault, but that keeps the players from feeling to bogged down. Fighting hordes of monsters, uncovering sinister truths and saving the world is not only quite a bit easier with a partner, but also a lot more fun. To sweeten the deal, the Fable games allow you to marry your significant other and start a family, and even buy and decorate a house together.
