I agree about the Marios, I hated Sonic. The MD have Virtual Racing, Micro Machines and some Ferrari and Lotus games I think, but I don't know if they were exclusive or not.
Streets of Rage is amazing, I still play it from time to time Theres also Golden Axe and Shinobi which I think were both exclusives and Earth Worm Jim, but I think that was cross platform.
Yup, I can delete the N64 from that list, in my mind it was released prior to the PS1, but it was actually 2 years after it.
