I can’t be sure but I seem to remember vaguely someone at Nintendo telling me that there was a company or something called StarVox in Germany, and because 'F' is pronounced like a 'V' there they had to change the name to avoid confusion. I think by the time the Star Fox Command and Star Fox 3D came out the company was defunct or perhaps the lawyers simply decided that there was no product confusion any more. The only story I know is the 'StarVox' one, because it was an interesting problem - which is why I remember it. - Dylan Cuthbert, StarFox dev
Like Mr. Cuthbert said, those days are now gone. StarFox has its rightful name over in Europe. The Lylat Wars name is now just part of Nintendo history.
