Dead or Alive and Last Bronx and VF2 and Shenmue Demo to prove sheep wrong it "can't do 3D/can't do polygons good/Sega threw in a 3D chip 1 minute before it shipped/it was 3D underpowered" middle finger debate ender. Definitely most of the games you guys mentioned, great picks.

-Panzer Dragoon
-Panzer Dragoon Zwei

-Street Fighter Alpha 2
Virtua Fighter (it looks "not good" but it seems to play Arcade perfect, better than its successors on Saturn imo)

Sega Rally

The Legend of Oasis

Radient Silvergun

With these titles and Sega in nostalgia mode, the Saturn mini will also destroy the ps1 mini. Then its DC mini vs PS2 mini, hmmm dvd feature won't help out there in 2019 !
