BF3 lighting is terrible in the way it's completely overdone. The engine would have potential, but they put all the effects up to 11 and the end result is just that - overdone. The graphics in that game in general are pretty rubbish, especially the textures and models, all that's done really good is some explosions and the haze/stuff-flying/fog of war effects they got going on. It really helps moving about because target acquisition gets really hard sometimes, which is great. Seeing people in HoS is too easy most of the time. And no, it's not because of the zoom.
The high contrast BF3 has hurts my eyes, I play 2 hours and they're red and watery, I much prefer RO2 in every way.
I have a particular fondness of the animations and ragdolls in RO2, they're awesome. Look at that german falling on his knee while grabbing his intestines spilling out of a hole in his stomach, and then falling down on the side while whimpering. It was a perfect kodack moment in a wargame, no other game ever portrayed death so chillingly well done. And it wasn't a scripted death-animation, other than the grab-stomach-move, it was all done by the ragdoll.
Also, gore works really good coupled with the suppression system - I was crouching in a trench and this guy
was standing up behind me and got hit by a mortar and he fell in - instant 100% suppression, and not just in-game suppression.
Edit:
This is probably the most creepiest post to post on Christmas. I don't really have an obsession with death, despite my steam screenshot library consisting of dead people and nuclear explosions. Really.
