This question is very important to me too. I install games for two reasons: 1) Reduced wear and tear on the disk drive/laser 2) Reduced heat and noise output. Both of these are important but #2 especially so as I live in a small room in a house with other people so keeping the temperature down is good for me and keeping the noise down [the disk spinning causes a lot of vibration noise in the room below] is good for them. I'm really hoping that either the whole game can be installed to the HD like most games, or at the very least [if it's two disks] we can install disk 1 to HD and disk 2 to a USB just like with GTAV and watchdogs [i'll happily take a little increase in loading/pop-in times over the heat and noise of it being read from the disk.] Bungie, please tell us if we can install the game so the disk stops spinning shortly after the start of play.
