2002 Xbox is actually a Dreamcast Pro or Dreamcast 2 if you want to be precise.
It's funny how Dreamcast are using Windows CE as their API and lead to bad port of early AM3 games to Naomi and Dreamcast . Many games like Virtua Fighter 3 and Sega Rally are worse than AM3 Arcade, while Naomi is more powerful than AM3 arcade . Also the lack of feature from Windows CE with DVD made Sega choose not to use DVD. I read a couple comment from the developer back then. Also Windows CE is expensive and Sega need to pay a lot to Microsoft.
If I have to choose. i choose Xbox original but if Dreamcast is still a thing i bet Dreamcast will be my choices.
