Panzer Dragoon is probably my pick for the Saturn. Starfox was a huge deal back then and PD was kinda like Sega's answer to it, much as Sonic was their answer to Mario.
Shenmue for Dreamcast for me as well.
Man I miss Sega sometimes, they really had a style all their own, in both hardware and software.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023. (And over 130 million lifetime)
