Just to elaborate on some of your observations, AstralTraveller.
Sadly, the FPS on the stream wasn't the best, but I think that may be due to the quality of the recording equipment/stream quality at the venue. Hopefully, the videos we'll be posting to YouTube on Monday will be much better.
Also, I believe the presentation was run on Ragnar's Macbook Pro, which normally is running the game totally smooth.
What I can tell you is that it runs totally smooth and looks completely awesome on my working computer (which is a standard, no totally beastmode thing). I feel such a delight every time I build and play the game outside of the Unity Editor.
And yeah, Zoe's ass is super! ^^
By the way, thanks for all the enthusiasm, guys!
