That's pretty much all there is to it. Seriously.
Firstly, gaming has absolutely nothing to do with anything except a premise for how these people meet. That's not a huge deal, except the anime makes it out to be otherwise, so it's blatantly misleading.
The first two episodes were relatively enjoyable; it sets up some interesting or somewhat unique choices in animation, and some of the characters didn't turn out to be who I was expecting them to be. With that said, later episodes drag each and every character through the mud, to the point it's physically painful to watch.
The anime rests entirely on the premise of five people--three of whom are *explicitly* made out to be extremely skilled in navigating social situations--being completely and utterly unable to communicate with one another. On top of that massively flawed premise, each and every scene was incredibly predictable, and not in the "familiarly reassuring" sense. The premise was neither believable nor cute; it was, in a word, stupid.
