http://www.geocities.jp/yadayo8/eiga/su.html I don't read Japanese but looking through the pictures I assume it is dedicated to movies and videogames and the way in which the former influenced the latter over the years. edit: and how games influenced latter day games too?
Do you mean how many games influenced other games? Well... I'd say all of them. I think you might need to narrow down that question a little bit. The site looked pretty neat, anyone know where I can get a Japanese language pack or something so I can actually read it?
I wasn't making a specific question, just an aclaration that the site may provide more info than film to videogame influence.
Since I can't read Japanese I use http://www.ocn.ne.jp/translation/ for translation. Paste the URL in the top box and click the second button from the left then the box on the far right and that's it. You should get a real good idea of what's been said. This translator seems to be the most accurate of the ones I've used.
