No, definitely not. In Skyrim you can't even fail quests. What choices does Skyrim have, the copy-pasted civil war? Destroying the dark brotherhood? You can kill Lucien when you first meet him in Oblivion.
>HURR IF I SAY THEY DONT COUNT THEY DONT COUNT
Point me to the Oblivion choice where you can side between two massive political factions with diametrically opposed beliefs that changes the people in power both locally and on a grand scale? You can't fucking do it. And there are unique perspectives and quests to play on each side, saying it is copy/pasted is disingenuous.
Yes, destroying the dark brotherhood is another good example, thank you, acting like a fag about it doesn't make it not count. What is a more impactful choice? Killing one guy or wiping the entire faction out and being routinely thanked by guards for having done it?
The Gildergleam quest comes to mind, the Forsworn Conspiracy can be solved by either wiping out the people in the prison and escaping yourself or by doing their bidding, and it has many smaller variations besides.
Dagon's quest allows you to defy him and spare the guy who runs the museum, same for the quest with the talking dog, Azura 's Star can become corrupted depending on your choice.
And like I said previously, almost every side quest that isn't directly related to a guild has two solutions/outcomes, a few are more linear, can you point to a single side quest in Oblivion with more than one linear outcome/method to solve it?
That's not counting minor variations and shit, like who can help you at the Thalmor Party or if you play as a High Elf how you can acquire Thalmor clothes beforehand and go as one of their own.
Listen, I am fine with people not liking the fucking game but at the very least you should know what you're talking about rather than being retarded.
