I kinda like this tbh, not only would the camera be less shakey (from anolog stike or mouse controls) but this may actually be a tolerable game for the unfortunate ones who get motionsick by watching gameplay. & since valve has the Hydra controls down, maybe some PS Move support may not sound far fetched anymore. Honestly I don’t care if i’m wrong, it’ll just be nice to have a valve game in my platinum collection. Roll on April! 
some people are unwilling to produce motion
Then how do they play games ?_?
Youg uys know better. The physgun thing… it’s another risky experiment they’re taking just like L4D2. What now? A PORTAL 2 BOYCOTT just because of the physgun?
The physgun thing is a stupid idea, I didn’t even like it in Garry’s Mod all that much. In fact, I don’t even like Garry’s Mod, so maybe my opinion is biased. Have VALVe released any information on how the physgun is going to be implemented on the PC?
How does a giant glowing laser-beam look too realistic?
The environments look somewhat unclean & the lighting seems a bit dark in certain areas, but it sure doesn’t look any more or less ‘realistic’ than Portal 1 did. Or are you just mistaking realism for darkness?
Guys, remember before HL2 came out there was a video showing the physgun in action?
Around 2:50

The gravity gun never actually used the phys manipulation. I think this is a similar video to show off tech for the motion controller. Not something that will actually be in game.
Either way, i’m perfectly fine with it.
Woo 5 more hours trying to find my way through a poorly designed building
I was answering the question literally, I don’t think they would be able to play anything. 
This.
It’s only custom content for those who buy P2 with the controller.
ZOMG BEGINNING SPOILER!
don’t worry I’m gonna mail you the one I steal after I play that segment
