I don't think that it will take both Fuel options if that makes sense (it meaning the game). I've not noticed where the game will link up with Nike.com and I've tried linking my account to it. The Fuelband will definitely link up to Nike.com. I'm sorry if that's a little vague. Let me know if there's anyway I can clear that up.
Hey man, saw your post in the Nike+ Kinect forum. You said you have a nike fuelband. Does the Nike FUelband feed data back to the Nike+ Online tracker and from the tracker back to kinect? I was thinking of getting a Nike Fuelband and using if when I'm playing sports and having it send info back to Nike+ Kinect training and have it work towards achievements. Having a hard time getting any info though.
