The design itself is great, it's just a bit off for something as iconic as Godzilla. He's had a fair share of redesigns, but Zilla was a bit too different in behavior and style that I can totally understand someone disliking it. Doesn't help that the movie itself was pretty mediocre. Still better than, like, Son of Godzilla and such but not as good as a better one. .
If the movie had been renamed "The Beast from 20,000 Fathoms" I think I'd have been fine with it, because if you ever saw that movie, it has more in common with Godzilla 1998 than actual previous Godzilla movies.
A game like Katamari Damacy, if only because why not. Have Godzilla roll cities up into a ball before nuking them with his radioactive laser breath, or whatever the hell it was that he had! Eventually, he can roll up the whole universe, and then we're screwed. But hey - at least he wouldn't have to worry about any damn illegal aliens trying to horn in on his action, right? Right?!?
