Wasn't it all mobile games? I'm pretty sure that was the exact market they were looking for. People with short attention spans that can't put down the phone, even while consuming other media.
I just ignored all the ads and any news, so you are likely correct. I did think that most of the games were mobile, but I must have been mistaken in thinking it was playable on Netflix clients on your TV or something.
I used to play Pac-Man on my old FireTV with the controller while I was killing time in the mornings before work, so I thought it was similar in that regard.
Based on the article: the AAA thing was supposed to be something new/different, but they closed it before releasing anything. I also haven’t tried the mobile games, but they should be still available, that is done by a different team
