If you have it, I suggest you play Worms Armageddon as it is still being patched by 2 friendly guys from the community who got the source code from the developers because they previously made amazing cheating/hacking tools but also fixed lots of stuff.
I believe that these features make W:A better than WWP, though the latter has a few features more.
http://www.nanacide.com/wahelp/info-updatefeatures.phpThe latest beta release is from January 2006, but the latest internal alpha is from December 2006.
The future goal with v4.0 is to merge both W:A and WWP with all the features if both games and many more, reintroduce a secure online ranking (which had been disable in 2000 due to hacks & abuse) and perhaps even make the game cross-platform compatible.
BTW, I'm totally addicted and can be found daily at the official Team17 forum (nick name "bonz").
