It's very good to hear how good this game is. I don't want to sound too degrading at all, but so far, for me, it's absolutely terrible!
Keep in mind, I actually like this game!!
I never really played Operation Flashpoint, and this game really feels like it's an add-on pack, rather than a stand alone game. The tutorial is far from detailed, as is the manual. Essentially, I'm struggling to understand the core principals of the game, and it's engine. I know that with time, I'll come to understand it well, and only then will I appreciate it... So I'll stick with it.
Until that time, there's no point in me trying the online elements. I've only just started the single player campaign, and I see I'll be a long time working my way through it.
It seems to be a game of opposites in many ways. The graphics are ugly... yet stunning at the same time! It feels counter-intuitive, but it's actually closer to the norm than almost any other game out there. The game, as mentioned by just about everyone that loves it, is essentially a beginning. I truly am looking forward to where it may go.
