While Sony has been revealing more details about their Playstation 3 online network, a few items have been unclear. Chris Kohler at Wired was able to speak with Jack Tretton at SCEA to try and clear things up, and one of the things they spoke about was if the service would support the “achievements” model as seen on Xbox Live. Tretton’s response was that there would be no “pan-platform” achievements or ranking system in place. Instead, it will be up to each game publisher to implement their own ranking system, and none of the launch titles will support an “achievement” type model. While Xbox Live Achievements have certainly added a new dimension of play to the Xbox 360 (to the point where high gamerscores are being auctioned and farmed) this doesn’t seem like a deal breaker on Sony’s part. Still, it does speak to the relative lack of experience that Sony has in maintaining and planning for a global gaming network.
