Wizards are reviving one of the most loved campaign settings ever next year in the form of Dark Sun - and just in case you're not convinced, 2 of the original writers are going to be working on it, so one can only hope it will remain true to its origins.
Appropriate thread necromancy! Dark Sun *is* coming back, and soon. If you want to have a look around the setting as it exists under 4th Ed rules, drop into the shop at 6 on a wednesday and jump into an encounter that's part of an ongoing drop-in campaign. Characters are pre-generated by Wizards, so all you need to do it play
