This feels like a strange thing since the Epic engine is available on Linux (I used it for dev just a couple of months ago).
I am not disputing the statement, the op makes a good case for atleast Tim being quite anti-Linux. I just feels really weird that the game store wouldn't ever get to a platform the engine is already on. It feels short sighted by Epic. Or I guess it just isn't worth the investment...
Valve also use HTML/CSS (or some form of it) for their game UIs using Panorama, but this doesn't use any form of web browser from my knowledge.
Indeed.
I feel like Electron encourages bad practice by allowing the developer to avoid the work of learning to write a native desktop app in favour of offloading the trade-offs of this decision onto their end-users in the form of poorly performing, bloated crap.
