Here's the official TV commercial for GTA IV, just released:
I was up until almost 3:00 a.m. last night with some friends, for no reason other than to cause havoc and destruction. One guy in the game stole a city bus, and then a few of us jumped on with him, broke out some windows, and did driveby shootings at homeless people and cops. I argued with an Australian friend of mine over who called shotgun, and then we shot at each other with shotguns. I tried to run over an old lady while I was driving a sports sedan, and I was so upset that I missed, I got out of the car, knifed her in the face and then teabagged her, all while my passengers were observing and chuckling. We went to an Irish pub and then someone shot an RPG at the liquor bottles behind the bar, and the building caught fire. We then ran outside and found a swarm of cops all shooting at us. Then we high-tailed it to the airport, stole helicopters, and flew around the Statue of Liberty, all the while shooting mounted .50cals at each other. Then I flew mine downtown near the MetLife building, tried to land on top of it, but I broke the propeller blades off, so I then jumped 59 stories to my death.
How many other games let you do these kinds of insane things?
