If you only do the main quest in Oblivion, then it won't last as long, but I'm currently up to 150 hours and I have yet to start the Shivering Isles expansion content (just finished Knights of the Nine expansion content). It's a great deal. I've recently discovered the difficulty slider and that's making things go faster, but it's the longest game I've ever played.
