I just watched the 4 new movies over at IGN showing off Half-life 2, and this game is very very impressive. (20 minutes worth of gameplay)

The rag doll effects are sick. And the levels and enviroments actually effect gameplay. Everything from cars to dumpsters can be used as a weapon.

I guess you have to see the movies to see what im saying.

Brevity? Maybe you can try to get some mirrors for these movies like you did for the halo 2 in game demo. This game deserves just as much attention.
