^That's potentially sig-worthy.
Hell yeah, GTA IV has some great moments. I jumped off a really high building (I think the highest) when I was doing free roam with a bunch of friends, and unbeknown to me, there was a dude cruising around in an Infernus (fastest car in the game FYI, non-players) below me. Had I jumped a second later or earlier I would have missed, but instead, I'm about to land on the front of the car and since it's moving I instead am barraged by the windshield; which breaks. The impact makes a sick crunch sound and flings me into the air, high, probably fifteen feet (I was at the height of an intersection light) and the whole time I'm moving up I'm spinning like... like... you ever seen when bottle-nosed dolphins attack sharks and they knock them out the water so fast that when the sharks spin their spines break? Yeah, like that except faster. He of course, slammed the brakes when this happened because he was like "WTF?!?!" and then he pulled a right turn very hard, after going from 200mph to 0 in like a half second, so his Infernus flips over onto the side and does probably two rolls before landing right side up. He climbs out, looks over to where I've just landed, and starts laughing so hard he doesn't notice when one of my buds takes his car as a prank; until he gets run over.
XD I love it when we just do whatever the hell we want in that mode.
