I installed Dragonborn today and i must say i really love the place. Actually i loved it so much that i fear that Skyrim became obsolete for my character
The place is more exotic and interesting with more lore even though only a couple of cities exist
The sense of danger in the wilderness has returned. This has to do with the fact that cities in dragonborn are not different cells. You can walk outside the city without the loading screen emerging
Many interesting secrets
One key aspect of that expansion is that many places and characters are the same compared to bloodmoon. The sense of familiarity especially in certain quests is quite powerful

Slightly disappointed by the Nordic ruins which were exactly the same like those in Skyrim. My level 65 character is fed up with draugr deathlords
Also i preferred forgotten vale quest that the last quest in dragonborn

Still the expansion is awesome.The only sad thing is that you cant purchase a house there So my character will be forced to stay in that tavern in Raven Rock

Actually you DO get a house in raven rock. You gotta do some side missions, but the house is the Severin Manor.

I forget which mission it is that triggers the initial questline to get the house. It might be the raven rock mine quest that starts it. But if you're doing missions for a redoran councillor dude in raven rock, you're on the right track.
Its like 3 or 4 missions and you get the house. The house has mannequins and weapon racks and bookshelves and the whole works.

If you want more detail on how to get the house, just google up Skyrim dragonborn Severin Manor and you should find the info you need.
