From what I'm reading here, most of you would go from having Sega make shitty games that sell 12 copies to making good games that sell 12 copies.
Daytona USA is the biggest-selling arcade game in Sega's history. A new Daytona USA game would be huge.
Daytona USA 2 didn't exactly set the world on fire, why would a 3rd game do any better? Arcades are dead in the west, we get enough racing games in Japan (Sega would rather continue their profitable Initial D series of games), and arcade-style racers don't have enough content for console releases (Sega Rally Revo tanked, despite being a good game).
