Sega CS1

Sega Consumer Research and Development 1 or Sega CS1 is a video game research and development division within Sega. Sega is thought to have consumer divisions every since they began developing for non-arcade systems, however it unknown which games were attached to CS1 during the SG-1000, Sega Master System and Sega Mega Drive era. During 1994, and the Saturn launch, CS1 gained notierity due to it's Panzer Dragoon and Sega Victory Goal games, which were showcases for the Saturn at the time. CS1 had two seperate sub-divisions known as Team Ara which focused on sports related games, and Team Andromeda which produced the Panzer Dragoon games. In 1995, Sega also established a PC division internally, dedicated to porting PC titles. In 2000 all of these divisions came together to establish Smilebit.

With the intergration back into Sega in 2004. The team has changed with non-sports operation becoming merged with Amusement Vision, and Amusement Vision staff completly loosing it's arcade focus. Therefore the current CS1 is a combination of Amusement Vision and Smilebit. For a brief time the Yakuza development team were known as the New Entertainment Department however that name changed to CS1 in 2008. In 2011, the Yakuza team got re-branded as Ryu Ga Gotoku Studio.
