Before we get started, those who have never played Monkey Island should probably just skip to the score at the end, dash over to Xbox Live Arcade and hit the download button. Unless you're a joypad-mangling mouthbreather, incapable of seeing past the next big shiny shooty game, you'll discover something that comes awfully close to being the perfect adventure game.
For those uninitiated, Monkey Island introduces us to Guybrush Threepwood, an ambitious young fellow newly arrived on Melee Island to seek his fortune as a pirate. First released back in 1990, he points and clicks his way through a series of puzzles, learning the art of insult sword-fighting and discovering the supernatural properties of root beer. Along the way he falls for Elaine, the island's feisty governor, and falls foul of the ghost pirate LeChuck, who has plans of his own for the lovely lass. If any of this sounds familiar then, yes, the Pirates of the Caribbean movies did borrow rather liberally - and rather cheekily - from this game in order to transform a Disney theme park ride into a rousing blockbuster success.
To say any more of the plot would surely spoil a wonderful experience best enjoyed fresh, so everyone who has yet to make Guybrush's acquaintance should do as they're told and go and play the bloody thing already. Go on. We'll still be here when you get back.
