Yes, the game is very polished. My only jab is that I feel the game has an identity crisis. In SWAT 4, the goal was to use everything at your disposal to minimize excessive use of force and to arrest the perps. In RoN, the perps seem to always come out guns-a-blazing thereby reducing this aspect of the game that was the heart and soul of SWAT 4: getting perps to comply. As is, you seem to constantly be in gun battles. If I wanted gun battles, I wouldn't launch RoN. I'd play Sandstorm, Ground Branch, or Six Days in Fallujah. All of which I highly recommended depending on your desire for "realism".
I will get back to RoN and keep trying to arrest perps. It's a very well-made game and a lot of fun.
