Grand Metropolis

Grand Metropolis is a stage in the game Sonic Heroes, and is a source of jokes for Radical Soda. The level itself takes place in a huge, technologically advanced city. You use the combined powers of your Team to get through it. Lots of the stage has you running down a road made of pure light, and other parts have you inside or on top of buildings. The joke comes from the video "Sonic Generations Level Mods" when Radical Soda tries to play the Classic version of the Grand Metropolis level mod, and since the mod is not made for Classic Sonic it loads the Sky Sanctuary Classic level. Later, he tries to play the Classic version of Sky Rail, but it again loads Sky Sanctuary Classic. Radical Soda then plays through while singing the Grand Metropolis song. This joke is later used many more times.
