>The Japanese manual includes the same map.
That's a half truth. The original FDS release didn't have a map and that is what sold the most. It's only the 1993 cartridge release which came with the map.
>The average gamer in Japan is about as skilled as the average gamer in America
I disagree because of one thing: the most played genre in Japan was RPG (starting from 1987 that is), the most played genre in the US was action games.
Of course players naturally would become better since that's what they played the most, THIS is why in the US magazines and players shat on action games that were too easy and praised hard games while at the same time, having walkthrough bundled with RPGs was the norm (unlike in Japan). It's simply a matter of being more used to something they played more.
There has been for a long time this opinion in the west that the Japanese players were "hardcore" but that's only looking at things through the spectrum of the niche that were famous for doing exploits, rather than looking at the norm. It's like how the PC-Engine is memed to be the "SHMUP console" in the west but if you look at the numbers most best sellers were RPGs and Adventure games.
