Why doesn't my Morrowind look like the version they show in the screen shots on the website?

The only difference I can pick up are that the screenshots look more cartoonish. You sure there's a difference?

Could you be more specific?

A few shots include placeholder art. For example, there's a shot of the character holding a daedric longsword while looking at a Dremora and the sword model doesn't show up in the game (although if you look closely it was modified to become the daedric claymore). There are also a handful of even earlier shots which are actually early renders rather than actual screenshots: a Gnisis merchant, an open market in a very different looking Vivec, getting a gondola ride through Vivec, and a guar caravan. These may actually be in the concept art section, I can't remember.

There is some discussion in http://www.gamesas.com/index.php?/topic/1169964-new-morrowind-background-on-elderscrollscom/. Probably just some beta shots. Glad they fixed some of the textures and I'm very pleased they changed the HUD.

these are probably the screenshots in question;

They are early renders of the game. Created to show what direction they were going, and to test a possible HUD concept.

EDIT: doh, Hungry D already said this.
