No. The game was practically finished in the Quake 1 engine and then they went through the grueling effort to convert it all to the Quake 2 engine.
He should have just finished it like that and released it, then try to work on a sequel in the new engine.>>5152604
I always knew of Romero as very childish and impulsive (and part of that is why I like him), so I actually am not very surprised that he would get swept into that hysteria.
I don't think it's something worth holding against him, and I'm not a fan of him for his political leanings by any means.
The question is if he still feels that way, because I know he can change his tune over time on things, his feuding with Carmack ended not that long after Dai-Katana's failure.>>5154069
It's a convenient way to distinguish a kind of sword from a specific place and era, which is mostly very distinct from most western swords.
There are also more kinds of Japanese swords than just the stereotypical pattern welded kind with a long and thick curved blade, and since Katana doesn't mean anything else to anyone outside of Japan, it's a good shorthand rather than saying "Japanese Sword", which could actually mean quite a lot of things.
It's a quirk of language.
