Wow, that's pretty amazing. It still surprises me that GTA is so insanely popular and I had somehow never realized it before. I guess it's because when the others came out I was more of a PC gamer, so by the time it came to PC it had cooled off a lot.
I don't think the Halo 3 comparison is really fair, though, since GTA4 launched on two platforms.
Also the Pirates of the Carribean comparison isn't fair - GTA IV has made $500 million, and sold 6 million copies. As m.e said, that works out at $83 per copy on average.
Well Pirates is a movie, and what's the cost of the average cinema ticket? Certainly less than $83. Even if we say $15, that means 27 million people went to see it, so that's 4.5 times the number of people who have bought GTA IV. Saying $10 means 40 million people.
So no, not great comparisons, but the basic fact that it's the highest entertainment launch ever is still true.
