I just checked here and realized I already did most of the quests (non miscellaneous). Is this really all the quests or is there more? If it is all the quests I don't know how much longer I can play. I only put 45 hours in and was expecting more from my first playthrough.

There's probably more. The game has been out for less then a week and the CS hasn't been released yet. The wikis can be updated with proper quest information when Bethesda decides to release the CS.

Also, you managed to complete all five guilds, the civil war, the main quest, all sixteen Daedra quests, every quest in every city/town, and became Thane of all nine holds in 45 hours? I'm impressed. I've been playing for 70 hours and it feel like I've done 30-35% of the quests.

There's infinite quests.

how do you even become thane of a hold? I've done the main quest, 2 guild, college of winterhold, civil war, and half the daedra quests and a few in every city/town. How do you know you've completed only 1/3 of the quests? How many questa are there anyways?

Um...you just made this topic...
