About the only thing that BC2 needs to show it's dominance over the competition is allow the kind of crazy fun that 1942 had, what with people riding on vehicles in all sorts of crazy ways. I never played it, but I saw plenty of videos and some of it was just flat-out cool.
In the end, just let me ride on the back-end of a tank, while prone, getting my snipe on WITHOUT sliding off due to game mechanics. MMMMMMMM.....chaos.
