I dont know why bethesda does not make a better morrowind game with better graphics while it has lots of funs... For example by using the same engine with oblivion...Would you buy such a game if they did so?

Morrowind is done and finished and Bethesda are not going to revisit old locations. They are moving on and hopefully the next game will be announced before too long.

If you want to suggest ideas for that then post your thoughts and ideas in http://www.gamesas.com/bgsforums/index.php?showtopic=1051579.
