(CNN) -- Ben Vu's parents and older brother fled South Vietnam by boat in 1975 -- in the chaotic and violent final days before Saigon fell to communist forces from the north. The family emigrated to a small town in Nebraska, where Ben was born, but the story of how the family escaped 38 years ago this month became part of the family lore -- real-life bedtime stories of daring and danger young Ben never tired of hearing. Three decades later, Ben started his own company, SkyVu (pronounced sky-voo) Entertainment, and used these stories as his inspiration for a mobile game called "Battle Bears."
