"Seeing lots of speculation about #tesv game engine. It's brand new... and it's spectacular!"

:o what are your thoughts?

I heard it was a modified version of the Fallout 3 engine :mellow:

Lets hope its a new engine! even an updated fallout 3 engine would be good for me.

It would seem so - bethblog is a pretty reliable source. :laugh:
