I don't love some of the things I somehow find myself doing when I play this game. It's fun to watch the blood spurt when you've taken someone's head off with a sniper rifle from ten yards, but i wouldn't say it nourishes the soul, exactly.
On the other hand, pinching a tank is a brilliant laugh; as is shooting-down police choppers. It seems like an illicit thrill, which just adds to the fun when things really start to kick-off
Best enjoyed in small doses, like any such game.
