These extras aren't as fun as the core content is, but we didn't expect them to be, and they will keep players occupied and entertained long after the credits roll. There are new TV shows (most notably the anime satire Princess Robot Bubblegum, though it goes a bit long), new side missions (helping out Luis's childhood friends in a gang war, doing favors for assorted characters, working at a club for Tony, etc.), and new radio programming. Of course, The Ballad of Gay Tony also features more of all the little things that make Grand Theft Auto fun, with the exception of the grainy visual filters from The Lost and Damned, which are gone in keeping with the lighter themes. The kickboxing matches don't make their way into the game's online capabilities, which is surprising if not very disappointing (see above).
Free mode includes parachute challenges and the new military vehicles. The deathmatch modes feature the new weapons, and the races include nitrous. Whereas Johnny's motorcycle opened up lots of new avenues for Rockstar to run down, Luis is, physically at least, the same thing as Niko: a reasonably in-shape adult male capable of stealing cars and shooting things.
The adjustments to multiplayer are milder it's pretty much the online GTA you know and love, with a few tweaks.
