I am currently replaying all the games in this set and they are amazing. Find myself staying up really late just to see what happens next. Really good story and cinematics are just a awsome bonus on the addictive gameplay. Best time to get it as it will last you till Diablo 3

The battlechest comes with Diablo and Diablo 2 + expansion

These games are terribly addictive, simple (you play mainly with the mouse), yet complex in its simplicity. These games define the dungeon crawler genre and are a must have in every gamers collection. The graphics dated well and it is highly playable even today. Last time I logged onto battlenet, there were 36,000 others playing. Oh did I mention the online multiplayer is free? Well it is, the only problem I have had with the game is the multiplayer servers can be slow sometimes, and are unlikely to be updated.

Diablo II: Battle Chest is an amazing package. Diablo II and with the Lords of Destruction expansion pack offers a game with an amazing amount of depth in story and character development. The Battle Chest package comes with a strategy guide helping you get through the game if need be, but more importantly helping you understand the different development paths you can take your character.
