The 1996 arcade game Sonic the Fighters, which was known as Sonic Championship outside Japan, is a fighting video game developed by Sega and it will be included in Lost Judgement. You can see the arcade cabinet for yourself in the Sonic Central presentation above around the 3:19 mark. This isn’t the first time a Sega game has been included in a Ryu ga Gotoku Studio game, as the first Judgment included six Sega titles such as Space Harrier, Motor Raid, Virtua Fighter 5: Final Showdown, Outrun, and others. Sonic the Fighters has you participating in one vs one battles with characters from the Sonic the Hedgehog series. The game was built on top of the 3D fighting engine for Fighting Vipers (1996), an earlier fighting game by Sega, which is also playable in Lost Judgment. Sonic the Fighters was eventually released on GameCube and PS2 in 2005 through the Sonic Gems Collection. It was then re-released in 2012 for PS3 and Xbox 360 with additional playable characters and an online versus mode. Lost Judgment releases on September 24 for PS4, PS5, Xbox One, and Xbox Series X/S.
