LibGDX is pretty much alive, https://libgdx.com, I guess you keep 
referring to the old site.

Yes it probably has been shadowed by the facts that the original 
author kind of left the project after being burned with the 
Xamarin acquisition and shutdown from the original RoboVM project.

And the tiny detail that nowadays Unreal and Unity are mostly 
free beer for indies, alongside their GC implementations, 
graphical tools, the preferred teaching tool at game universities 
around the globe, with first party support from Microsoft, Apple, 
Google, Sony and Nintendo on their OS, VR/AR and gaming platforms.

As for Verona, it is Microsoft Research language and it is mostly 
paperware in 2021, did you forgot to read the link?
