The Sega Dreamcast & Original Xbox Connection

The Sega Dreamcast (1999) has become a cult classic gaming system. Very popular at its release competing with the PlayStation 1 and Nintendo 64 but quickly faded in its short life span. By the time the Microsoft Xbox was released (2001) the Dreamcast had been discontinued. Sega then became one of the major third party developers for the Xbox game console. There are great franchises that began on the Dreamcast, many of them moved to the Xbox exclusively i.e. Jet Set Radio Future, Shenmue II and Panzer Dragoon Orta, even the Project Gotham Racing series derived from the Dreamcast game Metropolis Street Racing. The design of the Sega Dreamcast also had a great influence on the Xbox. Both have similarities in hardware such as being internet ready for online gaming, sharing similar controller layouts as well as 4 controller ports. The Sega Dreamcast ran an optimized version of Microsoft Windows CE (with Direct X) as the operating system. Surely, Microsoft took notes and learned a lot from their operating system being associated with a gaming console.

At one point the Xbox was even planned to be able to run Dreamcast games, with Isao Okawa, then-president of Sega, having several meetings with Microsoft founder Bill Gates over the subject. -Sega Retro
