It's good. It's this years Brothers-like, although it isn't as good as Brothers. It's cute, has beautiful art and a great atmosphere. A little too much of it is you running away from something, and some of the collision detection on environmental hazards is a bit off, along with some wonky AI in places.
I finished it in about 2 1/2 hours getting all of the videos. (Only a couple are off the main path.) It's nice to feel like you've learnt something along with playing a game... The documentary stuff is well worth watching.
@bweadcrwumbs: It's definitely not on the shorter side of telltale episodes, don't have an exact number for you but I think it took me a bit more then 2 hours start to finish? Thoroughly enjoyed it too, was getting kind of bored with the structure of their games but the humor helps quite a bit.
I doubt it. There will always be big games. It has just been an odd year. I bet The Order, Uncharted, Batman, Metal Gear, The Witcher, Bloodborne...and whatever Call of Duty/Assassin's Creed that comes out next year will all do fine.
