Maybe they need to take up the challenge of making a game that doesn't cause people to warn others about it? I dunno. People are always gonna people (be shitty) and that's something thin skinned companies need to get over, and quick. The Japanese made the games industry the powerhouse it is today. How many Japanese game mascots can you name? How many Western ones? To stop catering to that market because of a slee of bad reviews is just pathetic. Why a game developer needs to be encouraged to make a good product, instead of just buttoning down and doing their job of making a quality game to start with, send silly to me. Do I need my boss to praise me to do my job? No. But I sure as shit will hear about it if I'm not doing my job well.
I don't know how old your are, but I grew up playing Japanese games and I extremely rarely had a complaint about them other than the occasional difficulty spike, though I still finished them. Nowadays, I feel like I stop playing games and don't care about finishing them about 25% of the time. It's because they're crap and I wish I had read more of the reviews first.
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.
