Is it all that surprising? Xbox 360 director of product management (and all around snappy dresser) Aaron Greenberg told Reuters that it wouldn't be surprising to see Grand Theft Auto IV snag the top position on Xbox Live. While most Xbox Live gamers know that shooters like Call of Duty 4 and Halo 3 are generally the major competitors for the number one slot on Xbox Live, Greenberg said of GTAIV, "The multiplayer in this game is so well implemented that I can't imagine anyone owning a copy without trying to play it on Xbox Live." Greenberg is probably right about that. After all, he forecasts (correctly, we'd guess) that GTAIV will be the highest selling game of 2008, so there will certainly be plenty of players ready to go online. The question is whether or not players will continue to play once they've given multiplayer a try.
Will GTAIV take the top spot? We're going to go out on a limb and say yes. Will it stay? We'll have to wait and see.
