> I for one was thinking of what the first Touch Bar games would look like, or how it could act as a Rainmeter or MenuMeters-like at-a-glance view of my machine.
People are going to experiment with toys for the Touch Bar, sure, but nobody's going to actually try and publish a game for one. Not only would the audience be very small, but the Touch Bar itself is so limited that you're not going to be able to make a game for it that's worth buying. However, normal games can and should use the Touch Bar to extend the keyboard to do great stuff (e.g. RPGs could put Inventory, Character Sheet, Skills, etc as buttons on the Touch Bar, or use it as an alternative input for controlling some types of abilities).
As for MenuMeters-like at-a-glance, this is why I say the author doesn't seem to understand how it works, because the only way you could have an at-a-glance view in the Touch Bar is if you actually put focus on the app that provides it. You cannot have a background app that provides Touch Bar content (like you can for stuff in the menubar). The foreground app controls what's on the Touch Bar. So the only way to have at-a-glance meters on it is if the foreground app is the one providing those meters. And if you have to put focus on a particular app to see your meters, then it's not really at-a-glance after all, and it would be quicker and easier (and actually usable for people without Touch Bars) to simply have that app show the status on the screen when you give it focus.
