Hello I am not an ESO+ subscriber so I took part in the free week.
Firstly, yes it was a very good marketing exercise. Good job on that. There were plenty of people expressing the wish to subscribe or at the very least buy the DLC in Zone chat just before the servers went down. Once you go craft bag.... it is very difficult to go back.
I happen to be the kind of person that doesn't mind a little bit of innconvience to save money and I don't like the subcribing model for games. If I pay for a game I'd rather pay for the game not to pay to keep the game. I feel we are moving away from this model anyway.
However, I really did enjoy the DLCs even though I didn't have much time with them. I was supprised about how different from the base game they actually were. They definately felt more than just a new zone.
Thieves guild: Ahabs landing has this wonderful feel to it where I could run along the roof tops and the other than the gaurds spawning infront of me (which was a little frustrating) I really enjoyed the sneaking around in large houses. I feel the game really needs more cities like this one where you have multiple paths vertically and allies and large tresspassing zones. Feels most real than a lot of cities in this game. I didn't have time to explore outside the city, but from what i did see it was distinctly different from other parts of hammerfell.
Dark brotherhood: I didn't have much time with this one but the return of the kill cam from skyrim was enjoyable in a viseral way.. I love sneak kills. The landscape actually kind of reminded me a lot of home (Should I be worried about that?). White beaches and limestone outcrops. It is actually a little strange to have such a bright sunny zone be the setting for this. It was actually a little disappointing not to have the multiple paths and verticality of Ahabs landing but perhaps this is due to trying to match Obvilion.
Wrothgar: Majestic is the best way to decribe New Orisinium and Wrothgar. Again their wasn't much time to get deep into the zone but first impressions mean a lot. I feel like the reason this zone is so popular that is capturing feelings from both Skyrim and Morrowind. Snowy landscapes and jaw dropping visuals mountains and towering cities is very skyrim but added to that is the Orcishness of the place, The rustic, "this is built to be functional not pretty" designs and the different way of doing things including being a king that puts you a bit out of place to get that outlander feels from morrowind. I liked enjoyed getting lost in New Orisinium just as much as Ahabs landing.
IC: I didn't have time to try this unfortunately

. But I am not against pvp. I am very interested in the story here as well.
All in all the DLCs really quite good, in someways it makes me feel rather disappointed in the base game for not having the features they offer but in other ways makes me feel okay with spending more to get them because they aren't just extra zones.
I have played Morrowind on the PTS, The story is probably on a similar level but the zone really adheres too closely to the original morrowind and doesn't take what was learnt with these DLCs. I have heard people say the sidequests are better and having been to Suran that is probably the case (that quest is so good). The Delves are very beautiful as well.
I want future zones to keep what these zones have and add to it. I want to have cities with multiple roof top paths and small alleys ways to get lost and not only in the theives guild zone I want to be able to climb through valleys and ravines and up to the top of mountains. Deep into caves and forgotten ruins. I want there to be thieves guild and dark brotherhood and mages and fighter guild quests within new zones. I do like recuring characters and them reconising you but recuring ...guilds would be nice as well so that we get an intergration of the game within itself.. and perhaps make you want to buy the others zones DLC.. *hint hint*
Anyway I had this open on my browser for hours without hitting enter so I should just get the conversation started....
