You don't have to even be a huge DBZ fan or a huge Dragon Quest/Warrior Fan. I only got through the 3 games. Everyone else evolved. I did not. Not since 1991!
Dragon Warrior 1 had a big impact in my childhood, and DW3 was huge before (?) JRPGs came to power (IE:FF4)
If it weren't for modern day BS and my waning interest, I would say that DW/DQ lit the spark for JRPGs in general. And that DBZ was the spark for the massive love of anime/manga that still is alight today.
