Just finished watching and I gotta say: kudos to ND and Keighley for putting this together. I was apprehensive going in but it turned out to be pure class.
I understand the "arrogant" talk, but I don't agree with it. TLOU was a great achievement and they have a right to be proud of it. This event gave many involved a chance to showcase their talents in a unique way, and wherever there's talent there will be haters.
Lately we've seen a litany of TLOU-related threads, events, and features, sure... but not because ND is arrogant. For one, they won a huge number of game of the year awards and produced Sony's best selling new IP of the gen (in addition to Uncharted), so they have the acclaim to back it up. Don't confuse simple marketing for self-aggrandizing. They have a new, much requested, version of the game releasing tomorrow for Sony's flagship system. This is a novel way of promoting it by celebrating what makes the game special.
