Do you have to play the entire "The Elder Scrolls III: Morrowind" in order to play the two expansions?

Todd H: No, no way. We would never make someone do that. Morrowind is way too big, plus that's really not in the spirit of the open-ended gameplay we try to do. You can go play the new expansion content at any time during your game of Morrowind, and you can move between the areas of Morrowind, Tribunal, and Bloodmoon as much as you want. It's a big, seamless world.
