The main thing that turns away potential fans toward Shenmue is this that Shenmue is much more exploration focused compared to other open world games.
Adventure focused games as whole have a small market. That is why publishers stopped making AAA point'n click adventure games at the end of 90s.(In my opinion Sega shouldn't have made Shenmue their "killer app" game since killer apps should be in a mainstream genre.)
That voice acting problem doesn't in anyway make the game less successful.(Since only the internet crowd cares about this problem. If english dub bothers people then they will just switch the dub to japanese instead of complaining about it 24/7.)
Good localization doesn't make a game successful. Megaman X8 had far better english voice acting compared to other Megaman games and yet that game's failure was what that killed the franchise for a long time.
The main things that turned people away from Shenmue 3 were the lukewarm reviews and the fact that it’s the third game in a series that most of them have never played.
Sure, they could play through some ports of 20 year old games to get up to speed, but that’s a lot of effort for a game that failed to leave a positive impression on most critics and, by most accounts, sold pretty badly (at least according to the early reports on sales).
Spending $30 to play through two twenty year old games to get to a point where you can then drop another $60 to play a game that hasn’t reviewed particularly well is a big ask. Throw in the seemingly high likelihood that they’d be doing all of this to experience a story that may never reach a conclusion, and I’m not at all surprised that a lot of people skipped out on Shenmue 3.
If Yu and the team can make a top quality Shenmue 4 that garners good word of mouth and reviews well, that
might incentivize people to go through all of the hassle of playing through the first three games, but I don’t think it’s at all a given. That some people here want to give these people another reason not to play a fourth game by removing the English dub is a little beyond me.
I get that some people prefer the Japanese dub and that others think that the English dub is downright bad, but I really do feel that anybody who is advocating for the removal of the English dub is putting their own preference over what is best for the series.
Thankfully, I think that Yu realizes the importance of the game having an English dub - something made pretty clear by the decision to bring back Corey Marshall being made as soon as it became clear that the game had hit it’s $2m funding target.
This wasn’t some high end stretch goal that the team saw as a luxury if budget allowed - but a necessity. Indeed, if you look at the actual stretch goals for the project, the first five were all focused on making the game as accessible as possible to a wider audience (recap videos and subtitles).
