I don't really know if this if the right place to ask this question but I can't find a better one.

I'm moving to Seoul - South Korea for my studies in August and I was wondering with a friend staying in France if we could keep playing video games together. Many video games have different servers (Europe West, Europe East, America, Asia) because of the latency but some games have only one server so it might be possible to have a low ping even with great distances.

Does anyone know the common latency for non-hosted videogames between South Korea and Europe and if it is possible for us to find some games to play during my stay?

    There are many games you could play that aren't super latency-sensitive. Twitchy FPS games are likely going to be a problem, but anything more strategic, turn-based, or less precise, even many RTS games, are much more likely to be playable with a few hundred ms of latency. – Zach Lipton Jul 24 '17 at 8:37

    Since you are moving to Seoul, this is a better question for Expatriates – Jan Doggen Jul 24 '17 at 10:07

    Just a "fun fact" that the lower boundary will be ~57ms, which is the amount of time light needs to travel from Frankfurt to Seoul and back. – problemofficer Jul 24 '17 at 15:27

    @problemofficer the speed in vacuum to optical fiber is 1.48 so the lower boundary is 84ms. – chx Jul 24 '17 at 21:37

    I'm voting to close this question as off-topic because it has nothing to do with travel. – David Richerby Jul 25 '17 at 17:20

While South Korea is renowned for the Internet speed inside the country the international situation is not rosy. The only land neighbor to the North is neither friendly nor advanced so no fiber runs that way. You could run a short segment to Russia and then run a cable over there to have a short distance but it's just not economical. Instead, most of the traffic to Europe will travel over SEA-ME-WE_3 -- there's quite a lot of money to be made en route compared to a cable over the endless Russian taiga.

But that's a long and circuitous route resulting in much higher pings than a nice, straight cable with few routers en route would result in. Looking at http://verizonenterprise.com/about/network/latency we have UK to Korea around 270-300ms. http://zhiguang.me/2016/05/10/latency-between-aws-global-regions reports Frankfurt-Seoul as 266.154 avg. http://wondernetwork.com/pings reports 298ms Frankfourt-Seoul, 306ms Paris-Seoul.

Compare this to http://ipnetwork.bgtmo.ip.att.net/pws/network_delay.html the 141ms between San Francisco and Hong Kong over more than 11000 km compared to the 8540 km between Frankfurt-Seoul. In fact, if you use some of the links above you will find that the San Francisco-Europe pings are also 150ms so if you go Seoul-Hong Kong-San Francisco----New York-Europe -- you might still end up around 300ms so it's possible some traffic goes that way instead of the direct fiber all around. Certainly the 266ms doesn't, that's not possible but those close or above 300ms just might.
