A team of class action attorneys has launched an investigation into complaints that Halo 3 was falsely marketed as a high definition product, but does not actually render native high definition resolutions. These complaints are that, although Halo 3 was advertised as having a 720p resolution (720 pixels), it natively renders at 640p (640 pixels) and is simply scaled up to 720p. Read more about it here. If you purchased the Halo 3 game, you may be entitled to recover money.
