One of Lucasarts' masterpieces, and a greate game in its own right...
This game is a ton of fun. The story starts out strangely enough; you are Manny Calavera, a "person" who works in the Underworld for the agency down there that brings people over who have died and tries to sell them a travel package to the afterlife. While Manny is trying investigate why a great client was shifted from his responsibility to a rival's, he discovers the LSA, the Lost Souls Alliance, an underground alliance group trying to break through the money hungry agency that Manny works for. Manny ends up joining, getting himself into more than he bargained for. I'll stop there as to not give away too much of the fantastic story of this game. But the real reason I loved this game is that it isn't like any other adventure I had played before. I had played Myst, Riven, Zork Nemesis and Zork Grand Inquisitor before this, but none of them had such a great plot, such a great interface, and only Zork Grand Inquisitor had as much humor. Thats what makes this game special. The web of story, humor (intelligent and immature alike), puzzles that don't get you frustrated (like Myst), a great interface and great graphics (for the time, but anti-aliasing makes it still look amazing compared to todays games) combines to make a great game that is the second adventure I've seen for the PC that IGN gave over a 9. (Grim Fandango got a 9.4 and The Longest Journey got a 9.3).
If you love or even just sort of like adventure games, get this game now! If you've been curious about adventures, this is the game to start with! If you haven't liked adventures in the past, try the demo (54.4MB) and see if this is different from the games that turned you off of the genre. Overall this game is a AAA game and is tied for my favorite adventure game of all time (with The Longest Journey).
