Easy question.... Diablo 2 LoD is only one of the best games I have ever played in my life! It's made by Blizzard and has been on market for a very long time, a few... wait 5 years and it's still sellin' like crazy. There is Diablo, Diablo 2, and Diablo 2 Lod. (The LoD stands for: Lord Of Destruction). LoD is the expansion set to the origanal Diablo 2. I reccomend you buy Diablo 2 before upgrading to LoD. Why? Well to find out if you like the game of course.
