Fair points, but again I played alot of games from indie, unknown and mainstream from all regions and from my experience, Japanese games generally feel the most polished and fluid. I look for and experience all types of games often. It seems like that is the general consensus worldwide amongst most gamers as well even if they prefer Western games. If there is something from Western developers on par with Ninja Gaiden Black for example gameplay-wise, I'm sure someone would of discovered it by now and praised it significantly for that achievement. Not saying it don't exist, but it's just an observation.
I mentioned fighting games because they are generally very difficult to make and that's why there are so many terrible ones in history compared to other genres. Japan has made a lot of highly rated fighting games for example. The West, not so much. The ratings and reviews for those games are basically proof that most people think Eastern fighters are just better. On the other hand, Western developers are really good at shooters and I think most people regardless of their preferences will agree. Again, I am looking at preferences from other gamers as well and I just feel like different regions excel at different types of games. Sure, there are opinions and partiality with certain types of games of course, but I think there are facts backing it as well.
See your projecting your opinion worldwide which is nonsense considering many people are unattracted to those games specifically because they don't like the combat or find it engaging, at best youre talking about reviewers most of which who review them he really have a bias, but the market and common conversation doesn't generally agree with a single things you said. The same can be said for fighting games as well, which is why the two biggest franchises in the genre are not in the same category as other games, and even before the last 15 years, the western ones even the sports ones, generally sold more despite some neutral lacking reviewers giving the Jap games 9's. Though several reviewers you may notice, not all but many, IF they even tough games like you mentioned, never give the a similar high rating even if they liked the game.
The bott paragraph is interesting because it shows a lack of knowledge. There are way more trash fighting games from Japan than the west because the west barely touches the genre.
It's not because they are hard to make either. When the genre post SFII and MK was selling, a bunch of games were throwing together templates which is why from either region many of the bad games had similar mechanics or played near the same. You're confusing lack of interest and trying to cash in with difficulty.
I repeat, the two biggest franchises in the genre, are outside what you claim is a complex and difficult genre
Like I said before, it's not, it's basically a private club or cult with a bunch of games expected to share at least core mechanics and fundamentals to a specific fanbase so that you can pick up and learn quickly another game. Many of such games don't sell very well and are niche, with some better sellers being heavily discounted quickly or given away.
Saying someone would discover it by now is a worthless statement because how are you going to discover something you are not looking for? You brought up NGB because In your preference it's gameplay selling point is an example of something you can't find in western games, were a western gamer can and does argue the same thing the other way for games you've likely never played. But in that case ai am betting you would take issue with that opinion telling them the same thing I'm telling you now. Like I said both regions have players that come to these absolute conclusions without considering other options and refuse to yield.
As for fighters addressing your 2nd paragraph, Devs have no interest in the genre in the west and even in the east since the 3D fad ended, when you had you have all those cashins. We have seen manly the same major companies in the genre for the last 23 years. Outside the games going away from the usual formula, there's been almost no evolution or overall improvement.
Your mindset is exactly why mainly japanese devs are going heavy on mtx and cashgrabs with releases having shallow content, because many of the games are aiming specifically to the FGC knowing they have guys like you they can get money from without having to have notable jumps in between releases. Very little facts in what your saying, even hardcore fgc guys have been complaint the last several years about everything I just said.
If you're an outsider dev what is the point of jumping in a saturated pile with another games unless you're going to do your own thing, which is risky in any genre, and hope it catches on and attracts a larger audience? What returns are you looking at only making your own slightly different KOF? Those are the main reasons people and devs are not caring much for the genre. If it wasn't for the DBZ brand name, the same fighter from Arc would not have done 4% of the numbers. Before that game no dev would look at Arc game sales without walking 3 steps back.
