I'm optimistic about this, while smartly skeptical for the same reasons zoog is. But that's saying something. This is literally the only 6DoF game I've been somewhat optimistic about since D2. And no surprise, as Matt, Mike, and the team are heading it. I expect something finally true to Descent when this comes out. Now, it's no Inferno (my prospective Descent spiritual successor). But it's obviously not trying to be a radical re-imagining with level design that boldly explores 6DoF spaces in a way never done before. The aesthetic is nice, it doesn't look bloated, and it retains the spirit. But as zoog said, the trailer depicts much too much horizontality in the level design. And they need to get away from gray. All the walls in the trailer are grey. Don't make the mistake D3 did.
Descent: Underground on the other hand was probably the worst news in 6DoF development I've gotten in some time, and that's saying a lot. Pretentious, based on audience-drooling spectacle, and filled to the brim with cheesy audio taunts. Screw Underground, I'll let the masses eat it all up.
I'm unable to play the demo because I'm on Linux. Does the criticism basically sum up the demo as well?
