|Fast facts on Sega AM1 (2005-current)|
|Merged with: Sega AM3 (2008)|
Sega AM1 is the first arcade division of Sega Interactive.
After the Sega Sammy Holdings restructure, the various studios established in July of 2000 got the corporate names again in April of 2005. Sega WOW employees were split into consumer and arcade studios, with latter becoming Sega AM1. However alot of the development staff came from the Overworks side (Yasuhiro Nishiyama), due to many senior developers of WOW Entertainment joining the game company Paon. In addition many developers of late Sega AM3 joined AM1 in April of 2009.
The current AM1 ultimately became Sega's most successfull division, having a large amount of cash-cows across arcades and mobile, and a big amount of titles in different genres in general. Sega AM1 has many of Sega's and Japan's most popular brands on arcade and mobile, such as Initial D Arcade Stage, World Club Champion Football, Maimai, Sangokushi Taisen and Chain Chronicle. Sega AM1 has produced novel and innovative arcade machinery such as the Toylet or Nail Puri.
In comparision to sister division Sega AM2, AM1 also still has international arcade releases with various rail-shooters such as The House of the Dead 4, Let's Go Island: Lost on the Island of Tropics , or most recently the arcade edition of Mario & Sonic at the Rio 2016 Olympic Games.
