I think that'll depend on the region.
There are almost no arcade halls in continental Europe, and most people consider an "arcade game" as a machine that can only run early 80's games.
While in Japan, there are many arcade halls filled with state of the art machines with modern games on them.
As for consoles, China had a console ban for quite a while, and PlayStation dominated that part of the Chinese market once the ban was lifted.
Nintendo could have easily dominated China, but seeing how much they cared about the market:
・ 1 3DS XL with 2 pre-loaded games you're stuck with forever (unless you consider buying 3DS games from Taiwan or Hong Kong, which'd give you a few more games to choose from).
・ A China-only N64 model decades after it came out in the rest of the world and ended up having only a few games.
・ And now it seems Nintendo quit in China altogether (
last site update: 2012).
But at least it seems like they have improved their regional support for South Korea, Taiwan, Hong Kong, and eastern Europe with the Switch compared to the 3DS and Wii U.
And as for South Korea, they're mostly into MMO games, I can't really clarify here why.
Though it might be a similar case as with Russia, I recently spoke to a Russian who told me that only the games everyone in Russia are playing now are considered "good games", while everything else is considered "bad".
He gave an example of Minecraft being a bad game, not because he doesn't like it (he actually loves it), but rather because most people in Russia hate it.
So I suspect it's a similar thing here with South Korea.
