All Oblivion Remastered new and original voice actors – Destructoid

With the announcement of Elder Scrolls IV Oblivion‘s remaster, Bethesda noted that there were voice lines added to the new game. They didn’t revoice the whole thing, because how could you possibly replace Sir Patrick Stewart as Emperor Uriel Septim? The additional voice actors help to break things up.
One of the original game’s constraints in 2006 was memory. The sheer amount of voice files meant they didn’t have room for as many unique voices as they wanted. Now, every race has a unique voice actor to help keep it all fresh.
That said, they did make sure to retain a lot of the charm of the original. Oblivion has been memed on for almost 20 years now. They were keenly aware that getting rid of some of the sillier voice acting would be more of a detriment than not for most fans.
Here’s a list of everyone and who they voice in the original and the new game.
