Morrowind is a fun expansion.

Like the main quest
I enjoyed the side quests
Like both public dungeons
I have never run the trial, but I have not tried that hard to do so.
The area itself is very cool
I like the daily grind quests

Do I like Morrowind more than any other area?
For the most part the area is the same with the same kind of things to do. The public dungeons did get their own grind for a pet and a costume which was welcomed at least by me becasue it was something we could earn in the game and did not have to buy on the crown store.

The area looks really great. One of the best looking places to play. I guess I would rank Morrowind the best expansion release so far when compared to the other DLC's/expansions/chapters(Whatever you want to call them). Getting the XB1X and a external SSD has made me enjoy Morrowind even more becasue it is now a stable place for me to play without getting dropped to console screen. Also looks awesome.

CWC is something I am still playing through but so far I am putting this as 2nd best release right under Morrowind. Not sure if the CWC main story is better than the MW story as I have not finished it. So I have to currently put MW on the top.

Story is propably the only reason why I bought Morrowind. Ah no wait.. I just wanted achievement and title Star-Made Knight. I'm so dumb.

Clockwork City is more fun than Morrowind and lasted as long. If something costs as much as an expansion, it should BE an expansion. What was good in Morrowind was exhausted in two weeks but then all the irritations hit.

I enjoy going back to CWC. In Wardenfell i spend an absolute minimum to retrieve survey maps and get out ASAP. Morrowind caused me to stop spending into ESO. Now i just wriggle onwards as much F2P as possible.

Because my first exposure to The Elder Scrolls was Vvardenfell, and the lure of going back was too strong. I'm happy I did, though. The Wardens are... interesting. I mean, I'm glad I have them, even if they do under-perform.

The quests were immersive and interesting, the zone beautiful, lots of fun grinding the public dungeon for pet and costume. Lots of great delves, and a class that is dominating in PvP this patch.

Most of all, as a big pvp player, battlegrounds had kept me out of cyrodiil up until they added CP this last patch.

The only thing I didn't like about it was spending so much time in dreloth tomb urn farming for furnishing recipes I haven't found.

It sounds like you haven't even enjoyed all that morrowind has to offer. Do you often buy games, only play a portion of them, and then complain about a lack of content?
