For those of you old enough to remember the original Secret of Monkey Island on CD-ROM (I just barely fit into that bracket), this is a beautiful remastering of the game. With new hand-drawn graphics and voiceovers/narration, the pithy dialogue and storyline are just as fun as they were almost twenty years ago.
