How is ARMA boring?
Too realistic, and too much walking. And the enemy is always miles from you when you are firing at them. But I suppose that's the same as the first point.
To each their own I guess, I personally love the game. If you ever get the chance to do a LAN party with a bunch of people who know how to play and what they are doing you should do it, it's really a great experience. The campaign is boring, I'll admit, but nobody is forcing you to do it. I got started by a group of guys inviting me to a 27 person LAN party, and that was probably one of the best gaming experiences of my life, so I've always had a good view of it.
