I have realized how insanely huge this game is, and the fact that my entire lifetime will not be enough to experience 100% of it, especially when you have multiple choises.
I have a level 41 warrior with whom I just completed the main quest.
I also have a level 21 thief who completed the Dark Brotherhook questline.
I have just started a new character - a caster, and my main goal is to finish Mages College questline.
When I have done that, I might go back to my warrior to finish the Companions-questline, back to my thief to finish Thieves Guild questline. If I find the caster to be the most fun of them all, I might do some Daedric Quests and perhaps some other random misc quests.
The problem is that the thought of exploring everything from scratch with my new characters makes me dizzy. The same voice actors that go along again and again on different npc's annoy me. And the fact that when I complete a questline, be it guild or faction, it feels like it's essentially pointless and bear no fruits on the long term. This game has too much freedom and sandbox element for my taste and too few guidelines.
The size of this game is overwhelming, and even though I want to squeeze as much juice out of this lemon as possible, I simply don't have the time completing everything there is in Skyrim. Thats why I ask for help from experienced players. I want to know which quests are worth finishing or parts of the game worth experiencing. I know it's all relative and the fun may vary from player to player, but I need some guidance on which quests or quest-chains are most fun, so I won't end up doing alot of "pointless" misc quests that only give me some items that I don't need, and a simple thank-you-dialogue.
My definition of fun: The story should be fun. The area I am sent to must be beautiful. Puzzles would be nice. http://elderscrolls.wikia.com/wiki/A_Daedra%27s_Best_Friend <-- this quest was fun imo.
