It was released around the same era as Morrowind

Its a D&D game following suit from the Baldur's Gate series with a nice, new engine (though Morrowind look muuuuch better

). Still its best asset is the incredibly easy to use (though somewhat inflexible) editor, so as well as the excellent expansion pack(s) there are some quality mods out there - especially if you're looking for a good, deep narrative in your adventures
