This is from an MMORPG that I play called EVE Online. This video is extremely badass. This game all takes place on one server, with over 25 thousand people playing (100,000+ subscribers). You don't have to like the game, but you will like the trailer, I guarantee it.

The entire video was composed of actual gameplay, most of which had the HUD turned off for obvious reasons. My character is about 9 months old, this game came out in 2003 and is still winning awards and breaking records.
