Not a big Fan of saturn myself, don't know the games that made the console special.
Shenmue was such big deal for Dreamcast, the game was far ahead of anything at that time.
For me, in addition to Panzer Dragoon, the sequel Zwei, Nights into Dreams, Burning Rangers, and Radiant Silvergun were the main games that stand out on Saturn to me. I have a soft spot for the console, it may not have sold well but it has its own unique flavour.
And yeah Shenmue was mindblowing for its time. Soul Calibur also stands out as an iconic Dreamcast showcase.
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)
