4x speed server was my first RN game in almost 2 years. I've always wanted shorter rounds. This is a great idea and should become a standard, I believe it will.
And please don't forget about "English only" server like Rapid Rail I am playing right now. I love these English spoken servers for their diversity and unique touch of rivalry with people around the globe competing at any given time - with literally no time for sleep if you want to be the best And this is the only kind of server where all the people from countries, where RN game is striving for a significant foothold, can play freely without the need to use google translate all the time (been there!).
