Dark Sun: Shattered Lands

Dark Sun: Shattered Lands is an AD&D game based off of the Dark Sun campaign pack from TSR. In the beginning of the game, the player controls a party of gladiators. It opens up with a fight with a multitude of monsters in an arena. After the battle the party are sent back to the slave pens to wait for their next match. They talk to some of the other gladiators in the slave pens and escape (if they can) to help the free villages established by other escaped slaves. Eventually they must fight back against the totalitarian city-state of Draj and the large army they will soon send to wipe out all of the slave villages.

The game has a mouse interface and is basically point and click to move around, equip the party, talk to people, pick up things, etc. The gameplay is faithful to AD&D's rules in most cases.
