[Skybird]

I learned that the main quest of Dragonborn cannot be entered as long as the main quest of Skyrim has not been played.

A lovely major design fault.

I hate the main quest in Skyrim. I do not plan to redo it. Which means DB is only the various quests it offers beside the main quest. Good news is: no dragons.

Still: major design fault, imo. I assume most people playing a new character after some time do not necessarily complete the main quest once again, or do not like the outlook to do so.

(Without the Skyrim main quest played, you cannot enter the temple at the centre of the island, and do not get several vital communication options with people. I learned that from Google after I started to search for info on it, because I did not get into the main quest. A definite interest dropper, imo.)
