I saw a couple interesting videos on YouTube. From: http://www.youtube.com/user/DattoDoesDestiny/featured
DattoDoesDestiny - has lots of Destiny analysis, opinions and conjecture. Quite a few gameplay videos too.
Factions - ...may not be, what I thought they'd be...
Bungie has kept the importance of Factions within Destiny sorta vauge. Shocker! Anyway, the video below goes into some possible uses and value of Faction Interaction (Faction Interaction TM). I have almost NO experience with MMORPG types of games. So, some of the info here has me even more curious how it's gonna play out.
*He does some Destiny Calculus in the "Stats" video, not action packed, but interesting.
