Dark Sun Online: Crimson Sands

Dark Sun Online: Crimson Sands was a massively multiplayer online role-playing game (MMORPG) developed and published by Strategic Simulations in 1996 for Windows 95. Dark Sun Online was based on the licensed Dark Suncampaign setting for the Advanced Dungeons & Dragonstabletop role-playing game. It was one of the first fully graphical MMORPGs.

Dark Sun Online was one of the first fully graphical MMORPGs to feature a number of features popularized by later games like Ultima Online, such as nearly unrestricted player versus player combat. Due to the game's peer-to-peer structure, the game was susceptible to hacking by its players. Dark Sun Online closed in 1999.
