Lets see...

Guild quests:
- Dark Brotherhood, can't do
- Thieves' Guild, can't do
- Companions? They be monsters, can't do.
- College of Winterhold? Well I guess my paladin does cast restoration spells....

Out of Skyrim's 4 guilds, only 1 can even be considered by a "good guy".
--------------------

Faction quests:
- Stormcloak: protecting their culture and their freedom? Good! Blatant racism and elitism? No thanks....
- Imperials: protecting the peace and the well being of every imperial citizen? Good! Bunch of corrupt whimps selling out their people to a tyranical dominion? No thanks...

Im im a "protector of the weak", none of those factions are usable. One is full of hate and prejudice, the other has given up trying to protect its people's freedom. I understand that having no clear-cut situation is more realistic, but this is a fantasy game after all. Its about being the hero, and a hero without a cause... well thats called a fool.
--------------------

Radiant questing: Kill that guy. Kill those guys. Kill those giants. Steal this. Other then the Fetching quests and the occasional "catching an escapee", you basially end up killing every living soul you come across, with never an alternative option.


Sooooo... no love for the good guys?

to some degree i can agree with you. There very few quest lines that are pure good, but most other quests are about helping other people, although they are not very story driven.
