"subtract the NPC interaction", in a game majorly built on interacting with characters to progress. okay m8
Hellblade isn't a valid comparison by any metric, it has a much more limited scope than Shenmue III in many, many respects. Ninja Theory concentrated on providing AAA production values in an independent game (hence their partnership with several leading photogrammetry and motion capture specialists) but the end result is narrow, shallow, and short. (Note: this has nothing to do with the quality of the game, a game can be all these things and still enjoyable).
Hellblade's average completion time according to "How Long to Complete?" is 7 hours, Shenmue and Shenmue II land just south of 30 hours; and Shenmue III is likely to be the same. You can probably count the cast of characters on your hands, and it's largely a linear story/action game. Hellblade is unfortunately the go-to argument for people who don't understand that you can't have EVERYTHING on a budget, or simply don't wish to learn the push and pull that comes with handling resources in game development.
"The length of the game has nothing to do with the animations and design looking like complete shit"
Not even touching what this guy thinks is "shit", the length has a huge amount to do with it. Developing game content isn't free, and neither are dedicating huge amounts of time, technology, and human resources to great graphics. Unless you have limitless time, budget, and staff size; when you put focus in a particular area it may mean cutbacks in others.
Yu Suzuki in 2015:
"The game itself doesn't have to be gorgeous visually - a lot of the money these days goes into the graphics. If we perhaps compromise on the graphics and put more into the story, we can make a good game. The most important thing, to me, is that the game's interesting, and that it's something people want to play."
These days we have an idea of how these priorities have borne fruit. Several interlocking mechanics and gameplay loops that revise, re-envision, and refresh Shenmue as we know it; with still quite a few aspects under wraps and hints of better non-linear gameplay than the originals were ever able to manage.
I'm sure these cunts would still be complaining if Shenmue III was a beautiful but linear 7 hour experience instead.
