What is the yellow light of death?
Trust me I know all about having a messed up PS3 I have gone through two and am on the third one, and I am questioning how good this third one is.
If the hard-drive fails on the PS3 you may get a solid yellow led, this is referred to as the yellow light of death in response to the infamous red ring of death. The yellow light will show if the console is overheating as well, but the console shuts down so you don't it for long. The PS3's overall failure rate is about 1% and hard drives, although mechanical, have a very low failure rate (over million hours mean time between failure, so on average your hard drive would fail every 114years) which means you are very unlikely to see a YLOD, however one in three XB360 owners are unfortunate enough to see the RROD first hand. I was the unlucky one. I might just open up my PS3 and manually fix it myself!
D8 Awwww

Q,,Q but we're all brothers and/or sisters in arms and of the pack
Da [censored]?

Seriously, think about it as a werewolf hunting imagine all the werewolves getting in the way of each other it is a complete hassle, I would rather hunt on my own and not have to worry about someone else screwing up.
I am sure they DO hunt in packs at times, not only during the Bloodmoon. In Daggerfall, there was a quest where it showed a wereboar alpha pack leader. In Skyrim there was also a possible female werewolf pack leader.
"Here died (the) savage She-Wolf
Ulfeidr slayer (of) men and beast,
Savage leader (of the) Crimson Pack."-Word Walll.
Just don't have a big of a pack in all honesty. Personally, if I was living in that universe, I rather have my lover/wife as the only member of the pack, and possibly an offspring. Other than that, it would be too troublesome. It would be easier for hunters and villagers to detect more than two werewolves.
And who knows? Werebears can be in groups too! Remember in the Infernal City? I think there were two werebears hunting the mortals, along with a few normal bears. The tall Nord with the blue tattoos was also one of them, I think.
