There are media and cultural reasons why we play games in English. Dutch was a to small a market to dub all the foreign Movies and TV content to Dutch. Sub titles were and are more cost effective. Only programs for 0 - 6 year olds are dubbed. From that point you have some basic reading skills and can start reading subtitles on the cartoons, etc. This causes many Dutch kids/teenagers to consider content childish that is dubbed or in games fully translated in Dutch. Its not so much as wanting it in the original language, as most Dutch people would change a original German game to English too. English and American television, Movies and Music are far more dominant in the Netherlands, we barely see German content anymore, and are not as used to the German language as we once where.
