NMA is reporting that Fallout 3 was recently showed off in Taiwan. Lucky for us, the Taiwanese don't care about NDA's, so a couple of gaming sites posted a total of 145 screenshots from the demo.
Check out the two sites: Underone and Catchplay.
It looks like one of the sites has removed the gameplay shots, with the other one probably to follow. Luckily NMA has grabbed all of them and put them in their gallery. Check it out here.
Also, interesting to note that I live in Taiwan (which the Beth people know) and that demo probably would have been the closest to seeing Fallout 3 I'll have until at least late next year, yet there was no invite :-(.
