Get Skyrim. The elder scrolls can literally keep you entertained for years, while Zelda is now more of a rent... it might take up 30 or so hours of your time if you are extremely slow... then there is no replay value.
no replay value?! i detest such a comment!! i have replayed Ocarina of time over 100 times...it is a classic...but general amount of gameplay yes the elder scrolls has the best of any game in existence
