Games like Unleashed (and games that follow the general style like Colors and Modern Sonic's gameplay in Generations) is as good a representation as you can get without getting to fast it's unplayable. If his in game speed was a perfect representation of how fast he actually runs (speeds at or exceeding the speed of sound) the game would probably be unplayable by the average mortal. I've been thinking: how fast does sonic need to run in-game? (Caution, this may be slightly long, so bear with me)
