Thanks for your response and i completely forgot to state my own opinion,
Basically i prefer oblivion because for me i find the storyline much more involving and also i prefer the characters and the sanctuary,i fell that the questline in skyrim is far too short and with the characters involved in that storyline i fell that they could have done a lot more with them, also i find the quests in the skyrim DB too easy when compared with the oblivion Db (spoiler) as in the quest in which you must infiltrate the prison
Some of the DB quests in Skyrim, while not as hard as Oblivion, are not exactly easy. While "Hail Sithis!" was way too easy IMO, the quests where *spoiler* you have to assassinate a woman at her own wedding. Or the other one where *spoiler* you assassinate the son of a Penitus Oculatus general. These aren't easy, especially if you want the bonus content. However, the Penitus Oculatus is a sham compared to the Blades in OB.
