100%. I literally bought Echoes of Wisdom on Switch day one, dumped it, and played it in Ryujinx, installing mods to increase settings.
I have the money, and am willing to part with it, but prefer a PC Quality experience. Heck, I'd even pay more for a PC version that didn't have shader stutter and had real PC options.
That said.... I don't expect it. Nintendo is very stuck in their ways, which has pros and cons. On the one hand, we're getting good traditional game design, no layoffs, and no micro transactions, which is wonderful. On the other, we're getting outdated hardware that's just powerful enough to support their game design ideas (although we're even seeing the cracks there now), and a diehard dedication to the old console exclusivity model.
Mostly art things. I'm far from qualified to speak to it as an expert, I haven't played either version yet, but have friends who are very passionate about the topic.
I think the easiest way to explain it is to refer to this Miyazaki quote:
Even if you just look at the tutorial boss (I clipped a a YT side-by-side for you here), the changes they've made here to add detail are basically all... grotesque. Gross hanging flesh, some weird hanging nipple thing, it's a very different interpretation of the original than what I believe was intended.
This is obviously just one example, but it's this type of change that bothers purists. Now, mind you, I don't think this makes the remake trash or anything, but if you're interested in Demon Souls historically as the beginning of the Souls franchise, this kind of change is essentially revisionist history, and it's disappointing to me that the original game isn't also available in some way besides buying an old PS3 or emulating the game.
