After debuting in 1986 with its landmark arcade side-scroller Wonder Boy (later adapted for the 8-bit Nintendo Entertainment System as Hudson's Adventure Island), Westone went on to create the Monster World series, which saw several sequels across the Sega Master System, Sega Genesis, and TurboGrafx-16. The series was later compiled in the Japan-exclusive Monster World Complete Collection for the PlayStation 2, and eventually made its way to the Xbox 360 and PlayStation 3 with the 2012 launch of Sega Vintage Collection: Monster World.
Westone has entered liquidation process and its website has since shuttered. Sega has issued no word regarding whether the closure will affect the continued sale of Sega Vintage Collection: Monster World.
