Summerset has been a real treat I have enjoyed the stories and quests greatly I am coming to an end of the area however I think. What would be a good area to continue my journey and find quests and stories as good without to much of a letdown.
The game itself does not follow that order. Its starts all newly made characters in Summerset it seems
With the whole "chapter" thing ZoS wanted new players to be able to start out in the new content. Unfortunately they did not fix the discrepancies in the story dialogue to fit a new starting point.
There is story dialogue in some that refer to events to come in others.
The story is really originally designed, supposed to be played and makes the most sense story wise as stated in that thread: home faction + main story, Wrothgar, Thieves Guild+Dark Brotherhood (TG+DB might be able to be played at any point really), Morrowind, Clockwork City, Summerset.
