Fallout 3 Gameplay Video

IGN has made their E3 demo presentation of Fallout 3 (same demo as the other presentations) available for streaming and download.
Though he didn't reveal any of the details of the story, Todd Howard talked about the overall perspective of the game, how some of the factions fit into the world, and how to make use of the game's Pip Boy.

More than anything else, the demo allows you to get a really great look at the game's VATS and real-time combat systems, from incinerating raider gangs with laser rifles to blasting mobile sentry bots with a rocket launcher. Best of all, Todd really lets loose in a parking lot fight with the Enclave by making gratuitous use of his personal nuclear bomb launcher. That's definitely something you don't want to miss.
