remember you guys comparing mario kart to sonic sega all stars racing that has sega's top franchises, I think we should compare Sonic to the game that has Mario and the other Nintendo's top franchises. like how about the 3D fighting games from the late 90s: Super Smash Bros. VS. Sonic The Fighters, if you haven't heard of Sonic the Fighters Toast or Randomness just type Sonic the Fighters and take a look at it.
remember you daily toast a Nintendo Monopoly game? because I heard Sonic has his own Monopoly game too, so I say, how about the latest collector's editions of Monopoly from the 2000s the Nintendo version VS. the Sonic the Hedgehog version
how about the big 8 bit consoles from the early 80s, the original Super Mario Bros. which is the first launch title for the Nintendo Entertainment System VS. the 8-bit Sonic the Hedgehog for the Sega Master System
