Like we all know GTA 3 released in 2001 was the big break-through for the Grand Feft Auto series, selling 12 million copies. It was followed only one year later by the first expansion called GTA: Vice City in 2002 and three years later by the second, GTA: San Andreas in 2004, selling 14 mill and 18 mill respectively on the PS2 alone.
All these three games were made with the same engine but they took place in different cities. The total sales of these three games was 48 million copies if we include sales of Xbox versions. Notice that the two expansions, or sequels if you will, alone sold an amazing 35 million copies!
Now let's look at this gen's GTA. GTA 4 came out in 2008 and has sold over 14 million copies on the PS3 and 360. Not bad. GTA4 was followed 10 months later by the expansion GTA: Lost and damned in early 2009 and another 8 months later by Ballad of Gay Tony in Oct 2009. They were both made with the GTA4 engine, but they took place in the same city (perhaps with some new city blocks? I forgot). These two DLC expansions were later put together into a retail game called GTA: Episodes From Liberty City.
We don't know what they sold on DLC but the retail combo package has only sold 1.9 million so far on PS360. I can only speculate as the numbers aren't official, but I can't imagine that the DLC's sold more than a couple of million copies each. So total sales for two GTA4 expansions was probably not much more than 5 million, maybe 6 million? - compared to last gens 35 million! Also bear in mind that the DLCs cost like $20, much less than a full game like GTA3's expansions.
Why did Rockstar choose this route? Even including the rumoured moneyhat of $50 or $75 million from Microsoft for the timed exclusive deal (which equals the revenue you get from sales of about 2-3 million copies of a full priced game), the money Rockstar made from GTA4's expansions is peanuts compared to GTA3's expansions.
