I gave this a go and like TF2, it's pretty awesome looking at things up close. Objects really do feel like they are there and you can grab them.
I played at a point near the end where you're in the room with Breen, Alex, Eli and Judith. I could look around me and it felt like I could grab a hold of the basket thing Gordon is in. It also felt like I could punch Breen in the head as he appeared to be right there.
It's still sad when some people continue to go on about the Rift's low res and other issues. The thing is made for developers so these things don't matter at all. But there's always those that are always grumpy about everything (sooooo many of them here on BluesNews sadly) and will bitch, moan, and complain no matter what.
