I agree with the criticism of the trees on appearance, density, numbers, positioning.
No collision detection is also major.
I too much prefer the ROF trees - they look excellent down low. Also ROF has got positioning and placement correct so that it all blends better to create a believable landscape. (and I don't find their slight movement in ROF an issue or annoyance).
After their mea culpas on initial state of the sound engine and then state of graphics engine - and subsequent rewrites for both, I suspect that if truth be told they would also admit to a majorly screwed up landscape / terrain / tree implentation.
The difference in this case is I doubt if they will feel compelled to fix it.
