To me, TES games aren't "true" RPGs. To me, a "true" RPG is something like KotOR, for example; a "true" RPG gives the ability to choose, not just in your head but in the game itself, who and what your character is using things like alignment systems and a very good variety of responses to choose from in any situation.
That's my opinion - take from it what you will.
I agree, but I think Daggerfall and to an extent Morrowind were more RPG than oblivion, no not because they had dicerolls or were text base or any of that garbage people like to stir up when comparing previous titles to Oblivion, but because of some of the choices, to name a few
The end of the Mainquest....in Daggerfall
helping the spriggans or killing them
Keeping Fargoths ring or giving it to him for discounts at Arielle.
In Oblivion you weren't given any choices nor concequences
You will always be a holy crusader of the mages guild dispite whatever you personally think about your character, the Necromancers will always be the badguys and you will never be able to side with them.
the Fighters guild are always holier than thou and do no wrong,
Thieves guild will always be some offset of steal from the rich, and justification fo doing wrong.
the Darkbrotherhood quests mostly end in someone dying(shadow scale doesnt count its a personal matter), not that you failed a mission and now have to live with that consequence.
you can never join the Mythic dawn, your always the good guy.\
etc etc etc I can go on really, atleast in Daggerfall you could help the badguys to some extent and that still reflects in titles prior....albiet indirectly.
