50 Reasons You Need GTA IV - Part One

11. Bigger than ever!
This is the largest GTA Rockstar has ever undertaken, and it currently has around 150 game developers working hard to ensure that this next-gen Liberty City is the broadest, most detailed, we've seen to date. To put all of this in context, 2002's GTA Vice City had around 130 people listed in the credits (not including voice and motion-capture actors).

12. More detail
Because this is one city, Rockstar is packing in the detail. Building interiors are now realistic places, with breakable objects and connecting rooms littered with items. Outside, you don't just open a car door and nick off with the motor but smash the window, the glass shattering realistically, and watch as your character reaches in to undo the latch and open the door, sliding in and driving away.
