Diablo is one of those original and revolutionary games that only comes around once every 5 or 10 years.
Diablo has almost infinite replayability because the game randomly generates enemies, items, and dungeons on each new game. Every restart or replay is a completely new experience and will generate items and enemies that you might never have seen through your first playthrough. Further adding to the replay value are the three playable characters. You have the choice of playing as a close combat warrior, ranged combat rogue, or spell toting sorcerer, each of boasting different playstyles and strategies. Gathering loot and fighting monsters can turn into countless hours of enjoyability.
Diablo created a new type of game that has been imitated by other highly rated games in the years since it came out, such as Borderlands and Torchlight. If you are fan of RPG's or loot then this is a game that is impossible to pass up.
