Played versions ATM
There's a RtCW version 1.0 (uses same serverlist as 1.1 and 1.3) and there's a version 1.4. Both are great to play and it's highly recommended to install both versions as both have their own serverlist and different game styles. Also a modification Wildwest is still being played which also has it's own serverlist. The time with most player activity depends on the version. For an explanation and a list of current best (populated) servers, see latest Activity Report Feb2014.
