I try to like this game b/c I want realism, but I just can't. Everything is implemented so damn poorly and amateurish. The performance should not be as bad as it is for what's being drawn and what's going on. The HDR implementation is the worst I've seen. The gameplay is very fragile, awkward and just wonky. The AI is about as dumb as it gets. The animation is laughable. The only models that look good are weapons and military vehicles. All other models just look strange. No physics. An interface that is really clunky. Sure there's a lot of interaction to deal with, but the interface could be a lot better than it is. It's just not intuitive at all.
Unfortunately, they can't really fix any of this b/c the brain dead die-hards would complain since they're so used to it I guess and it would break backwards compatibility which seems so important to the die-hards. Their engine is just plan crap in every way. They really should replace it with something proven to be robust and cross-platform. The scripting language they came up with has the most bizarre syntax there is. Doing any kind of precise mission creating is a huge pain as well.
It's just too bad BIS is the only one willing to make a game like this. The thing is, they're going for a hard core sim, yet most things are NOT realistic at all. It's quite strange.
