This isn't about Japanese games or devs. It's about Japanese GAMERS.
People are always gonna people (be shitty) and that's something thin skinned companies need to get over, and quick
Answer me this: Given the situation described in the article, WHY would any dev, indie or 'AAA', want to get into the Japanese market?
I've made the decision to never buy new games anymore because I'm too often disappointed. I hope the Japanese, and other gamers too, create enough aggregate reviews to help me enjoy the games I purchase.
Unfortunately, if you were relying on the Jap gamers, all you'd get is the number of negative reviews each game has as an indicator of popularity, since they aren't leaving any positive.
Why is it so difficult to understand that the behaviour of the Jap consumers are breaking the review system as it stands? It doesn't matter how great your game is, if there's 0 chance for positive reviews.
