That's right I've never completed the main quest in oblivion besides going to Weynon Priory to tantalize the monk with the Amulet. Somehow I still got hundreds of hours out of oblivion. When I start playing Skyrim I'll probably feel a bit guilty.
Yeah I'm kind of the same.It's too easy to get distracted by all the other stuff,I started this current character at the start of the year,Altmer Atronach mage,with the intention of completing the main quest and playing a different style for the first time,as I'm usually a stealthy sort.The plan was to finish it before Skyrim came out.I'm still nowhere near finished the MQ,with only a few days to go,and my mage has slowly reverted into a jack of all trades stealthy sort with lots of magica.I svck at completing the MQ just as much as I svck at role playing,lol.As others have said already,the plains of Oblivion don't really appeal to me,I hate going through the gates too,they are samey,and a bit boring,and the ones where you have other people in there with you are really annoying.(I'm looking at you here Farwil,Huzzah!)I seem to hit the same stumbling block every time too,everyone's in the chapel in Bruma waiting for me to instigate the action,all sounds a bit too heavy and instead I'm being chased by as many Minotaurs,bandits and whatever else as possible down a road before turning invisible and watching them turn on each other.The main quest could have been dropped altogether and the Guild quests extended instead and I would have been just as happy with the game.Maybe i should feel guilty,I don't get as much time as I'd like to play,so I should make the effort to see the big scenes Beth probably put a huge amount of effort into when i get some spare time,it's just everything else is so much fun...
