Elder Scrolls IV: Oblivion Interview

ComputerAndVideoGames.com has conducted an interview with Bethesda's Todd Howard, in which the lead designer answers several questions about Oblivion, the upcoming fourth installment in the Elder Scrolls series. Check it out:
The game world has been described as "vast". How big is it compared to Morrowind, and roughly how many sub-quests or subplots will there be on top of the main story?

Todd Howard: It's big - in some areas it's bigger than Morrowind, in some it's not. There are over 100 very meaty quests and tons to do. I think scale is hard to describe. It's something you have to play to understand. We measure gameplay hours by the hundreds, not by the "tens." We're more focused on the quality of the interactions we're building.
