The Dark Sun campaign setting was sort of a flash in the pan when it came to the world of Advanced Dungeons & Dragons. It was a fascinating desert-oriented world full of unique people, monsters, and creatures, but is perhaps best known for its widespread use of mind-controlling spell powers called psionics. Although the Dark Sun realm never really took off, it did manage to spawn a couple of popular computer role playing games back in the early 1990’s.
Dark Sun: Shattered Lands was the first Dark Sun game released for DOS-based PC’s in 1993. Its sequel, Dark Sun: Wake of the Ravager, was released in 1994. Both games were put out by Strategic Simulations Inc, better known simply as SSI, before the company was bought out by Mindscape. These games set forth some gameplay styles that are still in use today. You can get them individually, or as part of the AD&D Masterpiece Collection that was released in 1996. Unfortunately, they both have a reputation for being buggy.
