rockstargames.com/socialclub and be ready for registration on April 15th. All you'll need is a Xbox Live gamertag and/or a PSN ID and an insatiable hunger for statistics. You've got one of those, right?
Once GTA IV launches, the site will offer the usual multiplayer leaderboards, along with a torrent of statistically generated functionality. The LCPD Police Blotter will show the most dangerous areas of Liberty City and the most commonly used weapons, using the "aggregated data of millions of connected players." Similarly, the Liberty City Marathon will catalog the "the amount of miles walked, driven, or swam -- to the number of bullets fired and stunt-jumps jumped" and will hold competitions amongst players using this data. Other sections will track players who complete 100% of the game (they can win an "ultra-rare" bit of swag); a Hall of Fame, tracking the various leaderboard champs; and The Story Gang, a "single-player leaderboard." Consider us interested. You could consider us even more interested if we knew the first thing about the game's multiplayer functionality, outside of the occasional rumor.
