I usually play on my PC, in the seclusion of my den, and my wife doesn't see the games much, but recently I was playing AC2 on the PS3 on the big screen, and my wife has been watching (while playing tetris on her laptop).
She asked me, just yesterday "Is this game really easy, or are you just a total bad ass?"
My response was, of course, that I am a total bad ass - but just between us, I don't even know if you CAN die in combat in AC2. I play stealthy because it's fun, but really...I can kill any number of foes, and I don't even have to play well.
And there's not even regenerating health.
Not an indictment of AC2 - just of lowest-common-denominator gaming.
