Is this any good?  It's one of the only games I've seen recently that's actually made me want to go out and buy it, except for maybe KOTOR 2.  Does it strike a good mix of tactics and action?  Don't really fancy the 'hiding behind walls' approach of Full Spectrum Warrior but I'm sick to the gills of Medal of Honor-style WWII shooters that let you stand in the middle of a field shooting Nazis with no consequence.

Worth a purchase?  Or can I borrow it off you, monkey_man?
