In the main menu of the game, there's a "scrapbook" feature with a brief history of Guybrush Threepwood's adventures if you haven't played the earlier editions. But the game (as far as I played it so far) contains a lot of characters and jokes that might be more fun if you've played the earlier ones. If you want to play them, there are "special editions" of the first two in Steam. They have improved graphics and voice acting, with the option of switching to the original graphics and back with the press of a button.
