Personally I don't really see the issue. We are an international community with English as its main language in a German oriented County and a German orientated Duchy. We have a few people who speak German and we arranged everything with them. We have our community and our own people to communicate with and when a problem arises we have people on both sides that can translate. You just have to make sure that the community you are joining is English orientated then and has (very) good relations to the non-english communities around you.

Not really had much issue before in online games as most people are quite up front about languages so you can at least make an educated choice and many people also have at least passable English as a commonality. There'll always be moments when people talk in their native tongue but thats natural. Only real problem can be in pvp - nothing like having your target caller speaking in a language you don't know. Here we have a very mixed Duchy of well over 200 active people spread all over Europe and as far as Russia... with a smattering from a lot further away. If I'm honest I just find it scary how good the English of most gamers is..... even our Russians speak fluent English (whereas the Russian they've taught me is probably mostly swear words but luckily I only ever try to use it around them!).
