DDO is nothing like the traditional pen/dice game. However, if DDO kept the same narration as it did when it was the pay-to-play Stormreach version of the game, then that adds a bit of a 'traditional' charm to it.

You alway had to follow the quest or else give the DM a week to design in the direction you want. There definitely is not an open world in DDO, the whole game is divided into 10 minute - 2 hour adventures. But then again, so was paper D&D
