Diablo 2 is a great improvement on the original Diablo. There is a great depth to the game that much improves on the original storyline of Diablo. There are now four fully populated cities with at least six characters in each who you can trade with and get advice from. Each of the cities has their own problem that you have to solve. You solve the problems by completing the quests given to you by the characters. There is an almost unlimited supply of weapons and armor you get. There are unique and magical items that you can only find once in the game. There is a slight improvement in graphics from the original Diablo. There a five video clips in the game- one before each act and one at the end- which are pretty good but take up allot of hard drive space. A full install of the game will take a little over 1.5 gigs of hard drive.
