Do anyone play this? Yes and no.
Yes, people do play this mod. Some time ago there was a thread reporting that 500 unique users had logged on to play FS that week, and that the number was increasing - and you will eventually find people on a server if you just keep trying. Fridays and Saturdays there are Community Games (see relevant thread here) which often draw crowds of 30-40 people.
But no... our numbers are nowhere near those of, say, Project Reality. Several reasons for this have been brought up, but I personally think the main two are that a) the BF2142 community isn't all that big to start with, and doesn't seem too much into playing or making mods, and b) that we had a 'bad start' with lots of stability issues, and this may have given us a bad reputation.
But again, there's still lots of opportunities daily for fun games - keep trying and eventually you'll find 20+ people on. There are more releases coming, too, and I think Hoth especially will draw a lot of people to the mod. Oh, and if you want more people to play, spread the word! Even small things like putting an fsmod.com link in your signature on other forums can make a difference. Starting threads advertising the mod can help, too.
FS is a great mod well-deserving of fame and popularity, and I'm hoping that one day, numbers might just pick up and stay up. Maybe we'll do a port one day, too. Either way, welcome aboard!
