The overall scope of Oblivion is an experience that is boasting a 200+ hour play time (get some sleep now!), but the main story mode will clock in at a bit shorter, somewhere around 20-25 hours (which is without any additional quests, exploration, or anything that makes this series great). Players will take on the role of whichever character they piece together, (picking from a pre-set list of species) as he/she/it sets out to find the heir that must fill an open throne in Cyrodill, the capital of Tamriel. Without an heir on the throne, the gates to Oblivion (a place similar to hell), are open, and unholy creatures are escaping and attacking local villagers. What lies ahead appears to be an experience unlike anything currently available on the Xbox 360.
