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.
Sorry I was defensive, I just do not see any point in comparing Skyrim to DAO. They are just too different.
Regarding DAO, I did not feel that my actions had any real lasting consequence on the game. I restarted four or five times trying to escape with the blood mage but I couldn't, and I just didn't feel like helping the "good guys" because frankly I did not like any of them, so I put the game away. Perhaps later quests give you more branching options, I don't really know because that style of play going from point A to Point B was not for me.
Regarding Skyrim, whether it has replay value depends on how you play the game and what you are looking to get out of it. If you try to play it the way you would play Dragon Age: Origins, going from point A to point B, following one quest right up with another, until you are finished with that quest line and then starting another quest line and doing the same thing, then yeah, it probably does not have a lot of replay value. But you do not have to play Skyrim that way.
Right now I am playing five different characters. An Altmer robed mage, a Dunmer nightblade, a Nord warroir, a Khajiit archer and a sneaky but tough Khajiit dual wielder. I could play those characters sequentially, rather than concurrently, and if I did that, I would get lots of "replay value" because I plan to play each of those characters for at least a couple hundred hours.
BUT, I will not do all quests with all characters. I will only do the mages quest with the Altmer and the Dunmer. I will only do DB with the Dunmer. I will only do Stormcloaks with the Nord. I will only fight for the Imperials with the sneaky but tough Khajiit. I will only do companions with the sneaky but tough Khajiit and the Nord. I haven't decided which character will do the thieves quest, but I will only do it with two of them. I may never complete the main quest. I have over 1,000 hours into Oblivion and have never even started the main quest (other than dropping the amulet off and leaving the fate of the world to others). So each character will only do about a third of the quests, but I will get 1,000 hours of play or more with those five characters.
The replay in a game like Skyrim is in developing your character and roleplaying it in an open world. I spend most of my game time wandering the land, gathering ingredients, hunting, looking for randomn encounters of all types, taking back my pelts, filled soul gems, ores and ingredients and crafting something out of them, visiting the local merchants to see what they have in stock and trade the stuff I have crafted, doing radiant fetch quests, etc. These types of things take up about 70% of my game time or more. Doing scripted quests takes up less than 30% of my time.
You cannot do any of these things in a game like DAO. So I just do not see the point in comparing the two.
