Grand Theft Auto IV [PS3]

Liberty City isn't as big as San Andreas, but is far denser. There's a lot to see and do and, like New York itself, very little wasted space. When you enter buildings, there are no load times -- you open the door and you're on your way up a flight of stairs to the roof. The only frustration is that there are literally thousands of buildings in the city, but most of them cannot be entered. With the exception of some clearly marked entertainment hot spots and mission-specific areas, there's nothing to indicate which buildings are open for business. So you might find yourself walking into a lot of doors trying to find which one will magically open. It's a little much to expect to have the interiors of every building rendered, but that doesn't make it any less bothersome that you can't go where you please.

The idea of a "living, breathing city" has always been somewhat of a joke in gaming. Every city in the past has felt artificial in some way. But Liberty City feels like a real place. And its history is built not only into the architecture and the people, but even in the music. There are more than 200 songs in GTA IV and many of them were recorded or remastered with specific references to Liberty City. You'll hear songs on the Classics station referencing the city, as if to suggest there's decades of history built into the culture. The soundtrack is an unbelievable blend of rock, pop, reggae, R&B and hip-hop. But more astounding is how well the songs and the DJs blend into the city itself.

It's this level of integration that makes Liberty City such a believable place. You won't just hear "America's Next Whore" advertised on the radio; you'll see posters when walking down the street and spot ads on the Internet. GTA IV takes aim at all of the modern forms of communication. Along with radio stations (a staple of the series) there are full programs and ads you can watch on TV and a fully browseable Interweb.

You could lose hours of your day surfing the 'net. That may mean sorting through junk mail, clicking on random links, using Love-Meet.com to find dates, or reading the news. There are multiple websites that cover news based on missions Niko's completed. You can read different takes on these events if you want to get an idea of how your actions are perceived in different political corners. You might never bother looking at all, but like so much of GTA IV, there are dozens of hours of content waiting to be either discovered or ignored.

To make itself more modern -- as opposed to Vice City and San Andreas which were "of an era" -- the focal point of Niko's world is his cell phone. You'll receive calls and text messages from friends and business associates on your phone. This is the mission delivery system. You may launch into a mission just by answering a call, but more often you will be directed to meet at a specific location to initiate your next objective. Or you might just have a conversation that serves no purpose other than to deepen the characterization of Niko, his friends, or even his enemies. The good news is that, just like in real life, you can talk on the phone while driving your bus through a police blockade.

The phone is also used as an organizer to remind you of critical events (dates with slutty online girls) and can be customized with new ringtones and wallpapers. And just as in modern life, the phone can become a nuisance. Date Carmen and she will constantly be ringing your digits and sending texts checking in to make sure you aren't sleeping with some other girl. Yes, there are needy people even in Liberty City. You'll also get casual calls during missions. You can always ignore the ring or you can pick up. It's most likely a friend calling and asking to hang out. GTA is a clever game brimming with hundreds of thousands of lines of dialogue and Niko will almost certainly have a pun-laced response to turn down a pal if he's in the middle of a helicopter dogfight.
