You have the task of finding the hidden heir to a throne that sits empty. Tamriel's previous emperor has been slain, and with no true ruler the gates to Oblivion open and demons begin to invade the people and towns of the empire. It's up to you to find the lost heir to the throne and unravel the sinister plot that threatens to destroy all of Tamriel.
Oblivion had a generic fantasy land and a uninteresting storyline about some big threat that everyone has to band together and blah blah. They basically got rid of the canon Cyrodiil jungle environment and Asian cultural influences for no reason (maybe marketing choice?), and gave us ridiculously repetitious dialogue and creepy staring eyes, auto-leveling of equipment & enemies to match the characters level (which can make the game really easy early on and really hard later on EVERYWHERE), and lots of hand holding that annoys many previous fans. Without much to show for it besides graphical improvement. Skyrim atleast feels fun with its archery, magic, large monster battles, dual wielding and smithing with lore consistent with what we previously knew about Skyrim.
