There's usually at least one full open mode server in the afternoon/evening for both NA and EU every day. On weekends, there's usually multiple full servers throughout the day.
MB2 sees fairly large surges of players whenever a new SW movie comes out, so there's currently even more people playing than usual.
Whenever I get on since the release of TLJ there is normally at least 2 full servers, lots of smaller ones. Community is great. There is always at least a couple games going.
We almost broke our peak record from 2 years back just a few days ago with 380ish players online at the same time. It is fairly safe to assume our current monthly players ought to be between 1000-2000 based on this alone. Generally when things are a bit more quiet, we have 60-100 players active at any given prime time hour for Europe/America.
I believe even an Australian scene has popped its head as of late.
