Playing the 30 Hz version feels, to quote some people in the office, 'broken.' There's something that can't be captured in screenshots and playing an adventure game where you just walk around and experience the world at the smooth 60 Hz.
Looks beautiful! As always, thanks for the GS uploads; whenever a trailer or gameplay footage is uploaded to YouTube, I instantly go to your site to see if a better version has been uploaded. Keep the quality content coming!
I've heard they tweaked the shooting so it was about the same between all the games. I don't remember it being that different between UC1 and UC2 (besides enemy animation and, i guess, gun-spray--actually moving the reticule felt the same). I'm not sure if they kept that the same though.
