Latest gameplay video from GDC.

Very nifty indeed Smiley

However, the gameplay video seems a lot like Half-Life 2's (from May 2003's E3) in that it shows you everything the engine is capable of doing, and that's it. But still, methinks this sets a benchmark for games to come. (and I wonder if it will take the place of "Best game ever", current held by 1998's Half-Life)
