I don’t think he has a great understanding of Australian prices.
The current MKW price of au$120 looks high but if you remove our GST and convert to USD with the average exchange rate over the last 12 months its equivalent to us$70.85. (Donky Kong is au$110 or us$65).
We are currently at a low point with our dollar so the conversion for MKW today would be us$66.49. (DK would be us$61).
Compared to the prices I’m seeing internationally it looks like Australia is getting relatively generous prices from Nintendo.
I’m pretty sure some regions can buy Nintendo digital games from humble store.
The don’t support my region so j don’t know what the range is like but I believe it as available for some places.
