From Gamer.tm: "Dead or Alive 3 seems set to be one the first original Xbox games to be made available to download over Xbox Live, according to the PEGI website.
According to the latest ratings published by the pan-European age rating board, Team Ninja’s beat-’em-up has been listed as an online game (essentially, one that requires an internet connection in order to access it – which includes downloadable games), and has been cleared for ages 16 and above."
