Sure, if you like linear games that take your hand and walk you through a story step by step then by all means rate DAO higher than Skyrim. I could not play DAO for more than an hour and I quit when I realized that no matter what I did in the Origins quest, it always took me to the same place and showed me the same cutscene of my friend using blood magic -- I wanted to go with him and use bloodmagic too, but the game would not let me. I tried to attack those snotty mages, but the game would not let me. DAO is a very linear game, and if that is your thing, then go for it. But if open world exploration and ability to do what you want is the measure of a good game, then it is SKyrim 10, DAO 0.
You're being defensive as if I were making an attack on the game, I only addressed "Replay Value" not how the game plays and its world, you're just inter-mixing all elements when that isn't what I was doing. Skyrim is a fine game, but seriously lacking in story progression, RPG elements and player agency (<--- especially this). If browsing an open world means replay value to you, I won't argue that. Replay value means playing the game again and getting different experience from it, Skyrim does not do that as neither did Oblivion. Fallout 3 actually does this much more than Skyrim with player agency even.
Sure, you can go anywhere and attack people and things in Skyrim, but do they actually have consequences? (no they do not). In DA:O, yes, it make a difference, and yes the battles and who you can fight are scripted, but role playing your character with the story and your companions and NPCs are not scripted; you have choices that actually change the game. And in this respect, Skyrim is scripted since you have no choice in the matter of the story and NPC interactions, other than to just do them or not. This is what I mean by replay value. I don't feel, and this is my opinion, that I can just roam around an open world and keep doing the same thing (which is mostly killing things) and find much gratification from it as far a replay value when nothing changes at all because of my actions.
