I really don't understand this obsession with still pictures of some game. Over and over again. Especially to-be-RPG one. It's so insignificant at this state of technology that I wonder sanity of those "reporters". Or to-be-players for that matter... There are so many things that they didn't show which are much more important for the quality of the game.
As for Radiant "whatever", it's nice to see they finally added some iteration and randomization, however profound that seemed. How effective it will be is yet to be seen.

I watched other day that clip in which Todd "the legend" is showing Beth's building - They have become to big to play on the fringes, so there is nothing, and I will repeat, nothing radically new from them quality wise. They have become fully mainstream, plus without worthy ideas. The worst kind of mainstream: the leechers. Good thing is, they have enough money to make pleasant gameplay to mediocre gamers, or force you to spent more money for next-gen video card to be able to play game that looks and feels like screensaver, or a demo for "Creation Kit". The new rule is not to enjoy playing the game, but to learn to program and script mods... For free of course... And I found this so rotten that it hurts, especially having in mind all those Beth's court battles about every insignificant shit. Their money is their money, but your time spent in mod is, of course, voluntary.

As for engine, as Sea said, it's pretty obvious it's some iteration of gamebryo lightspeed stuff. If someone wants to be sure, just compare
Ligtspeed's construction set with this "Creation Kit" when it comes out, its inner workings and similar stuff.
They can/will lie, but they can't lie that good. If you care at all, that is.
