Never said it was. Just that consoles sales of Hardware games are very healthy and in some cases better than ever .
What do you even mean? In anyway
context is key;
If you mean hardware sales, this is debatable. Last generation we had 3 consoles that have managed to sell over 80 million units, so far we have a healthy platform, a mediocre platform and a poor selling platform.
If you're going to argue that the PS4 + Xbox One are selling better than all consoles before it in the adjusted timeframe, again, context is key. The Wii U was Nintendo's best selling console and outstripping demand on the Wii in it's first three months, what happened after that? Complete collapse in sales.
What has happened to the Xbox One after January? Sales have fallen into the sub 200,000 units region (And 2 months to sub 100,000 units) in the US, showing that it is not in any form a healthy platform at the time being. Likewise the Playstation 4's sales have slowed down in the US and Europe and it's facing irrelevance in Japan. So far there isn't enough to suggest the uptake in Europe or America will make up for the declining sales in Japan.
If you're arguing about software sales, against,
context is key. One title selling well does not prove the market is in any way or shape healthy, it only shows that particular software is selling well.
Its a fad that is simply not sustainable for big AAA games . Sure for games that are only meant to be played on the move or the kill off the odd boring 10 mins - your typical smart phone game . But games that people like to play for hours on end , I can't see it at all .
fad
fad/
noun
noun: fad; plural noun: fads
An intense and widely shared enthusiasm for something, especially one that is short-lived; a craze.
MMO's have been getting more and more popular, not randomly exploded in the scene. Second they have been around since the late 90s/early 00s, therefore they are not short lived either.
Finally, how many AAA games do we have being produced at the moment? About a third of them. So the titles are not sustainable in many market places because the market is not there to support but a limited amount of them.
