What did the commercial show? Did it show gameplay footage? Did it show people playing the game? Or did it show a skit or something that had nothing to do with the game?
The commercial showed in the 9pm to 10pm slot on the CW, the time slot which features the new hit tv show Life Unexpected ("Juno meets Gilmore Girls!").
It showed gameplay footage.
It showed people playing the game (boy did it ever, no punches pulled there!).
It did the previous two things frequently at the same time by splitting up the screen.
It did not show a skit or in some similar way try to phail at advertising.
