As far as I know, they’re located somewhere near the German-Swiss-Border but in any case they’re from the Germanspeaking-Part of Switzerland, hence why the first YouTubers, who get material, are germanspeaking ones.
The Team consists of small newcomers, they’re not f*cking EA with shitloads of money.
I bet even that one single little stand on gamescom ate up a huge part of their PR budget.
So don’t expect them to come cross over the ocean for E3 that soon, except Train Fever becomes the next WoW, according to sale numbers and they develop other games to make money.
