I think nausicaa has been ripped off in more than a few games. The first real boss you face in crystalis on the nes is a giant bug in a toxic jungle. Looks just like the ones from nausicaa.
Yeah. I think Biohazard Battle wouldn't even exist if not for Nausicaa. Nausicaa was HUGELY popular in Japan in the 80s, topping the Animage character poll for something like 7 years.
