Now, this might not surprise you, but GTA IV is currently the most played game on Xbox Live. See for yourself: GTA IV Call of Duty 4 Halo 3 Guitar Hero III Gears of War Rock Band Tom Clancy’s Rainbow Six® Vegas 2 Iron Man Demo FIFA 08 Forza Motorsport 2 It does however surprise me. Sure the game has sold tons of copies, but with the single player element being so incredibly strong and with die hard fans of COD4 and Halo 3 still going strong, I didn't think that it would make it right to the top. The real question at hand is how long it will stay up there. The multiplayer sure is a lot of fun but I feel that a lot of gamers will slowly start making their way back to their favourite online T-bag fests over the next two weeks. It's really great to see that GTA's multiplayer element was built so well as developers usually leave it as an afterthought, especially when it comes to games like GTA IV where so much time and effort has been put into the games single player campaign. I hope that other developers take a serious hint from this and realise that building a strong multiplayer element to their game can increase both the sales and longevity of their product. I can only hope that the developers of Prototype, who have cancelled the games multiplayer to focus on the single player, are taking a long hard look at statistics like these.
