I passed. I recently bought both Kane and Lynch games and Just Cause 2 so I probably wouldn't touch this game for quite a while. The shooting just didn't feel anywhere near as intense as Kane and Lynch 2, even if the cover system does work lol. And I got my open world fix from Just Cause 2, which is actually quite good even if the vehicle physics are a tad wonky.
I did find the car physics rather impressive in the demo. I remember the first game wanted simulator worthy physics and I think they continued in that direction. It's no simulator, but worlds better than the GTA games.
Above all I wish the game was more like the first one I played years ago. It feels like a mainstream console game which isn't my taste.
