I tried that, it was great fun for some time, but the small amount of description given for quests - " has asked you to talk to , you should move." wasn't simply enough or deep. The game is made to be played with the stupid questmarkers and all the shameful simplifying for the mainstream audience.
For you these things are stupid; for others (the masses) they're useful if not essentials. Try to seen things from a different perspective than yours perhaps would help accepting some compromise,who knows.
Most people seem to reply that one should use the world, instead of letting it lead you, and I totally agree with that, but the point is that there is no original content in the world for use.
It is all very repetitive, find a random NPC, he/she asks you to find something, oh and it's in a dungeon, again. Kill a dozen of mobs till you find the object, done. I found Oblivion's quests more fun, too. It was sure going in the direction of mainstream, but still had some unique aspects and living, original content.
All NPCs in previous TES games were not there when you went to return that quest, some lied dead, some had simply disappeared, and it was up to you to find out what had happened, it was all more less straight forward.
For some reason I actually (even today) enjoy Morrowind more, you don't know whats around that mountain, or that lake, you'll have to go and see. Find interesting cities and villages in remote areas. And theres is not a copy-paste dungeon around every corner.
You know,things changes... and even here my suggestion above would help perhaps.
Dungeons are one of the strenghts of Skyrim by the way in terms of artwork/design. And you can find even story/quest related in some of them (many)
I repeat,i'm convinced that you've not played enough the game and most of all that you're too "nostalgic" of Morrowind and Oblivon to be in good faith in your statements here.
Is there even any quest not involving, or ending up, in a dungeon? Maybe a quest where I will have the choice to go and kill someone, or steal the object in mind instead, buy it off him, get someone else to do the job, become friends with the target and gain his trust?
Yes,there are some other quest that doesn't even involve to kill someone,like those of the "divines" - searching for them would be more constructive than moaning about a thing that you don't know in the depths. There are even the quests given you at the college to find books and magic anomalies; there are the Thieves/Dark Brotherhood guild radiant quests,there are the companions radiant quest that are very funny etc.
I remember in the past that a lot of people complaining about the "loss" of this radiant quests; now that we have them in a similar way to Daggerfall and even better realized no one seems to appreciate them.
This makes me stop and wonder about "some strange attitude" goin' on these forums and the net.
Skyrim isn't the perfect game,but complaining about one of his best aspects is childish in my opinion. Dungeons are the best of the Tes series; their only fault is that are too linear and with puzzles too easy; but this is the price that all we "aficionados" have to pay to a large-budget entertainment product for the masses like this.
I'm the first to complain about lack of depth/choices/consequences in Skyrim,but i'm conscious that even this is due to what i've stated above,so my hopes are minimal even in this regard for the future.
