Rockstar have provided PC gamers with Liberty City in all its glory. Rather than simply pushing out another port, they've included improved multiplayer support, a surprisingly easy to use video editor, and graphics that won't look out of place two years from now. The multiplayer alone makes it a must-buy.
Everything included with the console release is here, but better. The multiplayer is a blast, and you can easily lose a weekend to the video editing software.
The DRM and Windows Live requirements are irritating. Being unable to save without using a Live profile is unnecessary. No dedicated in-game content for PC gamers; let's hope it comes soon.
