A lot of great D&D Forgotten Realms RPG content. I own:

Baldur's Gate: Enhanced Edition (no DLCs)
Baldur's Gate 2: Enhanced Edition
Icewind Dale: Enhanced Edition
Planescape: Torment - Enhanced Edition
Neverwinter Nights Diamond (non-enhanced, Windows only)

So $12 for Baldur's Gate: Siege of Dragonspear DLC, Neverwinter Nights for Mac plus the DLCs, Pathfinder: Wrath of the Righteous. Which I guess still pretty good value so I'll buy it.
