*sigh* yay monopolies. But at the very least stay away from Japanese studios and publishers.
Not really a wise investment anyway. The Japanese gaming market is shrinking and it will only continue to do so going forward because of the population decline. They are supposed to "decrease to 100 million people by 2049 from where it is now at 127 million and will continue to decrease to just above 50 million by 2100."
That's not a market you concern yourself with in the long run, no insult intended to the Japanese.
