If you were questioning yourself on buying this game because one city is not enough, you might want to think again.  A recent article taking a look at GTA IV has some good news regarding Rockstar’s plans on future downloadable content.  Here is a quote from the article:

"Of course to call games as vastly ambitious as Vice City or San Andreas mere ’expansion packs’ seems childish, but nevertheless, the downloadable content coming for the Xbox 360 version of [GTA IV] has repositioned those games in just this way.

"[GTA IV’s expansions] are to GTA IV what Vice City or San Andreas were GTA III. Yes, Rockstar is clearly hinting at new downloadable cities; and the chances of them being London, Vice City or SA again are slim to none. So that’s new as in brand new. GTA IV’s Liberty City is the beginning. Think about that and be excited."

Since GTA IV is supposed to make $400 million before an expansion pack, Take 2 might be looking at an even bigger cash value for the game if this is true.
