It took me a little time to work out where the free transfers for a lot or realms that are currently available until the 5th, actually went to. The extensive realm lists gave me a hint that it wasn’t to an oceanic server, and I searched in vain as there was no US server list for Quel’Thalas – after rechecking the details on the realm It advised it was a Latin American Server.
Ahhh I say.. that 3rd tab that appeared some months ago. I rolled a Undead something on there once because Oceanic went down, and they didn’t. Besides General chat being half in Spanish and English it was interesting. They hadn’t had their realm long and there were a lot of real noobs round the starting realms, and then all these leet peeps from oceanic came and hijacked the chat. Oceanic came back up and we all went back home, probably much the the relief of the local residents.
I thought at the time the realm would have provided an interested language exchange, it was the 1st General chat that I had seen that was really multilingual. On our Oceanic realms we have alot of Asian origin players, but General chat, guild chat is all in English, most raiding guilds are English speaking guild run, and at best I’ve gotten to practise some swear words in Arabic, and Turkish and some Japanese on Americans stationed in Japan, but everything is in English. Our idea of foreign is the token member from wherever, and usually that member is very quite in Vent, or chats. Over my play time I have put a smattering of lobie toons across the US realms and the oceanic, and have played with people from all corners of the world, Yet English as the gaming language dominates
I often wonder how the European guilds communicate – and how potentially one server could have 30 different languages. What an amazing cultural exchange that would be. Or do they all speak English? ( I have developed a taste for Viking Folk Metal for Bands like Tyr, and Midnattsol, German-Norwegian type folky music mixed with Metal.) Alot of the Bands I love have European origins so would jump at the opportunity learn new words, if only so I could sing the song lyrics right instead of making unintelligible somewhat pitched vocal sounds. ) What’s Gank in French? Or Swedish, or Finnish.
I didn’t spend too long on Quel’Thalas, only to level 6 or so, but it was long enough to impress upon me the at least lingual uniqueness that this server had, so will these free server transfers encourage people to go over and it become a massive cultural melting pot? Or will the nature of potential language barriers make people hesitate. It will be an interesting realm to play on though, transfers from US and Oceanic were open.
I had considered transferring because I was at the point where I needed change for the sake of changing and people tell me I think too many things through too much, so I was going to dive straight in, but the multitude of different people in different time zones would not make it a very productive realm progression wise. So I didn’t transfer.
Will the change in the population change the uniqueness of the server, for good or for bad? A great thing about MMORPGs is the diversity, and the interaction with all ages and cultures, but servers seem to be cultural centric, but I would imagine Quel’Thalas would get to be an interesting conglomerate of all cultures

I’ve experienced two European servers, both having English as official language. And mostly it’s English that is spoken in general and trade. Sometimes there are people (probably kids?) spamming some incomprehencable messages in the channels, but it’s generally considered rude and not approved of.
I’ve been into pure national guilds, Swedish speaking, as well as international mixed up guilds, where we speak English, no matter of where we come from. When I’ve been in the national guilds, we’ve obiously used Swedish in guild chat and in guild-only parties and raids. But as soon as there has been a foreigner around we’ve switched to English. It IS a little bit easier to play in your native tongue, especially when you’re on vent or TS and the sound quality isn’t the best. It’s easier to understand instructions.
Still, to most of us, I think playing in English isn’t a big problem. The whole game is in English after all. If there’s anyone who can’t understand it they’ve probably been scared away from it at the first quest.
On the servers I’ve been the population has been pretty mixed. Since spanish speaking people, russian and french have their own servers, we who play at the English servers represent smaller populations. I’ve met quite a lot of people from UK, Scandinavia, Netherlands and Greece. But conversation is, as said before, normally in English and you don’t think much about the cultural differences.
Generally europeans adhere to the language set by the realm. If it’s an english speaking realm like most are then people will speak english with the occasional touches of foreign languages thrown in.
Outside of guilds it’s generally discouraged to speak anything other than english but inside guilds the majority tends to rule.
Europeans for the most part are very much like-minded people (although people like to argue about that) so the cultural differences are there but not very emphasized.
The germans and spanish tend to hide on their own servers so you don’t see too many of those around but they definitely speak german and only german on german servers ;).
