This may sound a bit stupid, but i have already read 3 stories of installing Halo 5 from the disc. I am on the east coast and intend on going to the midnight launch to pick up my Limited edition along with my elite controller. So like I dont feel like waiting an hour or 2 for it to install, so i preordered the game digitally as well and its downloading right now. Ill just use the codes that comes with my physical to get my req packs and armor goodies. This way it will be unlocked and ready to play when i get home and all ill have to do is install the elite controller software.
