I've played Morrowind and Oblivion and have Skyrim pre-ordered but have decided to take advantage of free Daggerfall to help pass the time till the 11th. I've heard so many good things... hopefully it's age won't kill it for me.

Standard tip for players coming from the newer games: Switch the controls over to the view based option and customize the keys to give you something like the MW/OB control scheme. I don't mind the default controls, but they're pretty ludicrous compared to modern games. Hope you enjoy the game!
