It may be less than palatable for some to realise, we are becoming a global community. Those who wish to interact with that global community just have to accept that a majority speak one particular language. Arguing which language is spoken more in a particular region is not really productive. If we went by sheer numbers of world population then the internet would all be in Chinese Mandarin. If you only speak a minority language (in terms of the internet and online gaming as a whole) you have to accept, there will be less opportunity for you. While I'm sure Russians are very proud of their nationality and native tongue and rightly so, the simple truth is, the majority of online gaming is in English and will likely remain so. I don't agree with excluding anyone, encouraging other gamers to join in with the majority will help everyone in the end.
Yes it's true Northern and Eastern Europeans often have the ability to speak German, but even more speak English, as well as German. I know a guy in Norway, he speaks Bulgarian, German, Dutch, French and English. When he streams on Twitch.. guess which language he uses? The majority of internet traffic is in English, the vast majority of games are produced in English speaking countries. The majority of European countries have English speaking TV channels (for entertainment rather than just news), the UK and USA generally do not (Unless you get them by subscription). Most of the successful Films and TV is produced in English speaking countries. The most popular music is overwhelmingly produced in English speaking countries. Abba, a Swedish group would have been unknown outside of central Europe if they had stuck to their native tongue. So it's just a fact, if you wish to engage globally, chances are you will have to learn to speak in English, and you will have much more popular media to immerse yourself in the language than we poorly served English speaking countries get. Look at HitBox, a streaming media company based in Germany, the majority of people by far who stream through HitBox stream in English. This move has been made successfully in other disciplines. All air traffic controllers have to speak English. Those involved in World finance and higher tier business conduct their business in English (or American). It's just a reality, no intent to denigrate anyone.
Here's something interesting. I speak a little German, Dutch, Spanish and French. When I visit those countries I don't get to practise as much as I would like.. Why? Because as soon as they hear my accent the majority figure out their English is far better than my feeble attempt at their language. Shameful I know, but it's just the reality of life.
