This isn't about something I need. As I've posted numerous times in numerous places I largely moved to PC around the time if the WotG release, and added Xbox to the platforms I play on not quite a year ago.
If you don't need it, you have no reason to be advocating for it. It doesn't help you in any way,

2} Release of this product through a backer-funded method is inherently profitable
It's not profitable enough. Even if those 38 people were willing to pay $100, I still don't think they would do it. And if it got to that point, you could just spend that money on a used xbox or PC that would run the game better instead.

"Shut up and take my money" just doesn't work with SE. I think we can all tell that from their payment system

It's simple: they want people to upgrade, and those people should upgrade. This game is going to completely outlast the PS2- Why stick to it to the bitter end when you can make a small investment on a newer piece of hardware that is certainly more useful than just for FFXI (whereas there are so many PS2s out there that don't even read discs anymore that FFXI is all they're good for)

The PS2 was a great system, and it had a great run. But it's time to move on.
