Bethesda 'demakes' Fallout 3 for Japanese New Vegas website
Well, sort of. The Japanese Fallout: New Vegas website is designed as a Dragon Quest-style RPG, presenting the menu and links as areas on a pixelated map of Fallout 3's Capital Wasteland, with each link leading to an amusing faked gameplay segment, along with a Japanese-language explanation of that particular game element.
It's designed to introduce Japanese gamers to the "Freestyle RPG" design of the Fallout games, but it also has the side effect of being awesome.
