While waiting for the 0.69 build to finalize for release, the RWR community is organizing another Big Match to get a lot of players to play online -- wait for it -- at the same time on the same server! The event takes place on Saturday June 30th at 7:00 pm UTC (GMT), so set all your alarm clocks ready so you won't miss it! See the actual invitation on the forum for details.
The game will be most likely hosted by a 100/10mbit server in Finland, so European players should be able to enjoy low lag in general. US East Coast is also known to have a playable ~160ms lag on this particular server usually, so come and join the match numerously!
On another topic about online matches, this magnificent little tool provided by JackMayol just began to exist recently to track RWR online players without manually polling the in-game server list or watching the server list in a web browser. Whenever a player count exceeds a limit you've set, this tray app informs you about it. Very handy for getting notified when the players are gathering around for a match on any public server!
