awesome demos?

hey, ive been looking around the marketplce for demo's but the only demo's I found that were actually good were dead rising, burnout paradise, turok, and call of duty world at war-I haven't looking through all of the demo's yet but I was wondering if anyone had any suggestions or recommendations.

Thx in advance

Battlefield: Bad Company had a great demo I'm not sure if the servers are still up anymore though.

Download them all

There's no reason to pick and choose, they're free so get to it
