Bungie: ''We kunnen veel leren van Call of Duty 4''
"We have a lot to learn from their success too, they did some very innovative things to keep people going and their experience-rewards system was something that we paid a lot of attention to,""I think it's a great game and single player obviously is fantastic... they did a hell of a job with their set pieces, of scripting certain moments that they were really sure the player was going to actually see and experience first hand. The way that they use those moments to craft the player experience...Halo has a lot to learn from."
