New Game! / One sitting anime

Ok, so I've just seen in one-sitting the anime ''New Game!''. It's basically CGDCT [cute girls doing cute things] and it's probably a genre most people should be quite familiar with by now. This anime isn't just very good by CGDCT standards, it's probably one of the best slice of life [genre] i've seen in a while now!

Have you seen it? What did you think?
Or if you haven't seen it, what anime have you seen in one sitting?
