The graphics of GD: RB are decent. More often than not you'll probably be too busy to notice since you will be glued to the instrument line that you're following at the moment. But I can safely say that the animations and characters are rendered nicely. This also features the band in different venues & styles depending on when each song was released during the band's career.
