Seems like a fairly equal amount of people in this thread that are 100% sure they read something
somewhere either confirming or denying dual-wielding shields, yet no one has come forth with any kind of proof, so until someone can provide that, I consider dual-wielding shields in, because:
In a game of choice, and the option to dual wield what you please. Why would Bethesda GO OUT OF THEIR WAY to not allow this? Seriously, it's more idiotic to say "No, you can't" because I can right now, so WHAT IN THE NAME OF THE GODS would stop me when I can grab 2 axes? Nothing
As for the guy replying to this with something about "making extra animations," since you can put a shield in either hand, they have all the shield animations for both hands, right? So there, they wouldn't have to have made any
extra animations for dual-wielding shields since they're there anyway.
