I know that Chrome stopped supporting UWP a long time ago, but I recently tried to play a Unity game and I just couldn't. I tried all the browsers, even IE which UWP itself suggests, however I couldn't run it on any platform?
Can anyone play Unity games anymore, or are they all useless now?
Thanks,
No, Unity is certainly not dead :) But the Web Player got deprecated in late 2015 after NPAPI support was dropped by most browsers.
It's still possible to develop for browsers in Unity by switching the target platform to HTML5/WebGL in the Build Settings. In contrast to the Web Player, HTML builds utilize standard APIs such as WebGL, asm.js etc. which allow you to run your application without installing any browser plugins.
Here's some info about how to build for WebGL
Another getting started document which also mentions some limitations you have when building for WebGL
