While browsing the net, we came across this thread at the popular (and sometimes extremely immature) GameFAQs that outlines everything from how to dupe items to how to find rare creatures and items to my personal favorite, how to access a test level on the 360 version by using one of the DLC patches! You can also find out two different ways to clear the 360 HDD cache and do some very odd enchants.

The thread also posts links to Oblivion sites and maps and more. If you play Oblivion on the 360, you gotta check this thread out...and tell em Rated-M.com sent ya!
