This is the best Milsim I've ever played. And I can't stress enough how much of a milsim this is vs just being another shooter. The learning curve is rather steep, but if you invest the time to learn, you will not be disappointed.

Make sure you have a good CPU before you get too crazy with creating your own missions though.

-----UPDATE-----

I nominated this game for the ateam award Labor of Love because its been out for over 5 years, and the Devs are still making and updating DLC and content for this most excellent of games.
