Thank you for you work!

It's easy to forget today, but the Sega home consoles were always secondary to their arcade business. The main reason the Saturn sold even as well as it did was because it was the only way to play versions of the heavy hitters: Virtua Fighter, Virtua Racing, Daytona USA and Sega Rally in the home, in any fashion approaching the arcade (though still quite cut down). Those Sega 3D arcade games were absolutely mind blowing back in the early-mid 90s, and the pace of technical progress and new ideas was unlike anything since.

And the Dreamcast was conceived from day one to make it easy to port games from the Sega Naomi arcade system, and those arcade ports are probably the main reason people still play the Dreamcast to this day.

Yup. Although sometime in the mid-90's, the home console business became more lucrative and Sega really missed the wave. Games at home were their own distinct art form: longer, more complex, far more replay value. Arcade games rarely have more than 15-20 minutes of content and this was true of Model 3 and Naomi games. Sega's arcade focus became a major liability by the time Dreamcast rolled around.
