There's a really interesting post/video up at [http://www.thenewgamer.com/archives/averaging_gradius.html]. Like many early games, it has a very controlled environment, so watching how different players play the level is almost a virtual version of people-watching. The video merge has also been done exceptionally well, and there's some really neat stats included at the end of the article. Makes me want to find a copy and fire it up, just to compare.
