You cant see how the controls are in a lets play video, or how audacious and annoying the DRM is, and most reviews also dont mention it. That is actually the biggest reasons I return or dislike games nowadays.
And yes, it takes me 1 hour to just get controls right in games like GTA 5 or ArmA. I actually played ArmA 3 4 hours until I returned it with a red face full of anger. I really tried to give it a chance, still do from time to time. Main reason were things that I would have never seen in a video, and most reviews didnt even mention them. In games like Total War Rome 2 you dont see how bad that game really is after 2 hours.
I think, and know from experience from many cases, that the vast majority of pirates wouldnt buy a game in any case, since they simply dont have the money. You can put up as much DRM as you like, they simply wont buy it, even if there is no cracked version for it for months. In some cases they can scrounge up money for a subscription game or 1 or 2 games a year, but thats it. There are several studies that support this too. If at all, piracy is actually free advertising.
I have given up on waiting for BIS to come back to their senses and do a real ArmA 2 successor.
