I love BF far more than any other shooter and I also downloaded the demo.
I have very little experience with console shooters as I generally stick to PC. So, my dual analog skills for shooters suck. However, since I now own a PS3 I was giving it a try.
Controls aside, the game is ok. Still feels like a BF game which is good and I like the destruction. Need to try it on a PC though so I can really compare, however, I'll keep playing the demo so I can get accustomed to the dual analog sticks.
