how many hours of game play was Shivering isles ?

This thread might be better in the Oblivion general. But in answer to your question, if memory serves it took me about, I don't know, 15 hours, give or take five hours, for me to complete the main quest. Not to mention exploration and other quests, which added many more hours.

Wrong forum, but it was pretty long iirc. I would say I spent at least 20 hours playing it. Of course everybody has a different play style so that is a vague guesstimate.

thanks guys

it was just a quick question dont expect allot of responses .
