New to Monkey Island? Back when LucasArts was called Lucasfilm Games, a creative young team introduced us to a pirate wannabe named Guybrush Threepwood in The Secret of Monkey Island. This led to a series of swashbuckling adventures where Guybrush became a Mighty Pirate™ (although not without continuing mis-steps), and the games quickly gained popularity worldwide. Monkey Island has returned in epic fashion this year with the episodic Tales of Monkey Island saga -- the first of which you can get free here.
(free first chapter really but should still be worth it)
