I know that the Black Mirror thing was a success, but I didn't even really like that. Gaming, and sitting back on my lazy ass to watch content passively are two very different mental modes.
When I want to play games, I put on a game.
When I want to get fat or fall asleep after long work day, I put on Netflix.
I have no idea how representative I am of the average subscriber, but if most people are like me then I would like to offer a big "I told you so" because it made no sense to me when Netflix announced that they were starting to branch out into games.
I mean, if Netflix has grown to peak numbers and needs new markets to enter, then by all means produce games but they might want a more suitable distribution channel like Steam or producing console games for mass retail etc.
