I have it, 2 friends from Hardcoregaming.org (former BF2 mod Project reality clan) used to have a server, but it kept crashing, and they canceled it. It's quite fun, but very time consuming.
I got very good at producing food. The downside to the game is that any settlement you build has to be checked on daily. My work schedule on weekends means I can not log in then makes for a lot of dead chickens and rabbits.
