Indeed. Forcibly removing them while the player already has the ability to do so on their own doesn't accomplish anything.
Kieran, I recall the quote you're talking about, it's from an MMN article released shortly after X Collection. And yeah, they did comment that they knew fans would complain either way on the topic of X6's voices, but that doesn't say that nothing else was at play in the decision. To merely force what is already within the player's power will not reduce complaining.
Further, I know for a fact the author of that article was either misinformed or speculating on a few points. They sited Sentsuizan's description as evidence that its input had been changed during development and later changed back, but in truth the X Collection description is identical to the PS1 description.
Actually, I prefer all the Japanese version stuff over the US version
I'd agree with that as a rule of thumb, but there are always exceptions. And for me, X5 is it. But generally speaking, I enjoy the US intros, while preferring the Japanese ones.
Going the opposite way, however, I despise XCM's US intro. Go figure.
Then there's MHX, which is pretty much just a matter of context. I actually prefer Don't Wanna Be as general listening, but believe the US theme is better fitting for the intro video.
