It seems to me that until recently (e.g. until the last 12 hours or so) the was roughly a 50:50 split between 2 and 4 player games. Now it seems more like 20:80.
Has this actually changed? And if so it it on purpose?
This has caused the rating of my bot to climb, BTW, as it seems to be better at 4 player games than it is at two player games at the moment.
