Arma Is arma fun?

As a general rule of thumb, Arma is tons of fun. There are various problems. For example, no matter what PC you have, it *will* lag. If the server is mildly populated that is.
As someone who only enjoys hardcore games, no crosshair or third-person etc. etc., you don't really have much of a choice in regards to server there. But, if you do find one, especially the King of the Hill ones, oh well. It's a blast!

Most populated Gamemodes are Altis Life (Which, different servers can sometimes have the feeling of a completely different game), earlier mentioned King of the Hill. And. Well. Missions. But Missions you can only do organized. That means, a clan, playerbase, whatever. And someone who will create those missions for you. Which is hellofa work.
