No I'm not, although pushing the boundaries is one way a game can sometimes change a console's image in the public eye. Neither Sonic the Hedgehog nor Super Mario World came close to pushing any boundaries on their respective consoles. However, they both do a lot more to how we think about those systems than some other game that is only notable for being popular or well known.
Think about what Pokemon did to the image of the original GameBoy compared to its earlier years, when it had been the system of Tetris and Super Mario Land. The entire public perception about the platform's relevance and target demographic changed instantly. That's a definitive game.
Sonic likewise turned the Sega Genesis from the console known only for better-than-average arcade conversions into a system known for speed, power, unorthodox games, and attitude. That's a definitive game. It's not definitive just because it was a popular game on the system. It changed the console's public image completely and permanently.
