Steve Ettinger opened the Seattle division of Realtime Associates in February, 1994, which was later acquired by KnowWonder Inc. in November 1999. Several staff from the Realtime contingent continued to work on handheld titles, and became the nucleus of what would be dubbed Griptonite Games, a name that was coined when KnowWonder, Inc. renamed itself to Amaze Entertainment. Griptonite's focus was on Game Boy Color, Game Boy Advance, and eventually some Nintendo DS games. In 2007, Amaze Entertainment and each of its internal studios was acquired by Foundation 9 Entertainment.
