I think we need a good feature video. That is most important.
Nowadays information is a lot faster and more direct, and people are used to only getting the core information presented, and if they want to learn more about something, they look for more information. It's not like you could say to the people: "Hey! Wait! Can I tell you something abot a game I play?" As soon as you write or tell them a few features and start listing up, they will say "Booooring!" and walk away, which doesn't have to do anything with the game concept.
Such a text is already too much for many players. But if you would put it into the medium which transfers most information in least time, moving pictures, you would have their attention.
I know, PR doesn't really want to attract those hyperactive CoD-kiddies which can't read such a text without dying of boredom, but there are many other players who behave similar, but they aren't, they just don't know it better. What chances has PR against games like CoD:MW or BF3/BF:BC2, in terms of fame and reputation? I just stumbled across PR by accident, over a subordinate clause in a forum. And I used to play games like ArmA, OFP, Ghost Recon, Rainbow 6, Insurgency and S?ldner - Secret Wars. Still, in all there years, I never heard of PR.
Make a video, make it "cool" (not dead serious, nice camera effects like the pan shot with fast zoom in which turns into a slow motion with this air sucking sound, letting the camera look into the gun of a tank, for example, you know what I mean), show some fighting, some real ingame footage, even staged, I mean: how often do you get to fire a 40mm into the back of a squad which stands crowded at a corner? On the other hand yesterday I threw a handgrenade on a squad of Germans firing on a distant target on Lakshar... I think I killed four and shot a fifth one, then I got shot myself

Something like that. It's at least what I imagine. I wouldn't recommend to make it too serious and "that's real war"-like...
