yea that what i wanted to know, and if i could just use my charater for it and play it like a add on
The answer is still no though. You cannot take your Oblivion Character and use it in Morrowind (or any other TES game).
It wouldn't be good if it would be possible either, because the char could be missing certain things you'ld like to chose, as there are more options.
In Morrowind for instance there are more different kinds of weapons that you can specialize in (like Spear, Axe) and you have Medium armor as well as Heavy and Light Armour. Also, the levelling system works differently and there are more skills, spells etc that are not in Oblivion (like Jump and Levitate: Yes you can fly!).
And the chars look different, fighting works completely different, and beast races cannot wear boots so clothing works different as well.
All in all, many reasons why you cannot use a OB char in MW or vice versa.
But still, Morrowind is a great game (just started a new char after not having played it for 2 years or so) even if you have to start from the beginning and I highly recommend it. It may even be better to start from the beginning, as there are many things you have to learn early in the game. It takes more timeto get the hang of it than Oblivion, plus there is less help with the quests (no green arrows).
