I think some fans feel the PC version has always been an afterthought, and also think that getting the game made by hook or by crook is the best outcome. In their mind EGS is fine because we should just be grateful it's being made.
It's just short-term thinking though, because if Ys Net had released a game that delighted the 70,000 people who backed this game, those 70,000 people would be back for Shenmue IV.
I think at this point it's clear to everyone with half a brain that the series is dead after this. Reviewers are going to eat it alive, half the fanbase is either pissed off or sympathetic with those who're angry, and the general vibe and consensus around this game is that it looks shit. Plus it's releasing at near full price in the same month as big hitters like Death Stranding, Jedi: Fallen Order and Pokémon Sword and Shield. Add in the fact that a wide gamut of people, ranging from GamerGate types to more evenly-hinged individuals, can all see how fucking shady this whole Kickstarter has been. $7m raised for... that, along with a slap in the face for the PC backers? No one in their right mind is buying this when the alternatives available for a similar price are infinitely more compelling for a multitude of reasons.
It's fucking dead, and the self-proclaimed "true fans" haven't cottoned on to this yet.
