Nearly a decade ago, Java was quite the popular choice for Game development. We had libGDX as the most optimal game framework, along with LWJGL (when low level was needed) and JMonkeyEngine was a fairly good option too. Now no one even talks about Java for game development, even for educational purposes
However over the course of time they all disappeared. Everyone slowly switched to game engines and C#
The arguement of “JVM slow, Garbage collector overhead” doesnt fit either because C# is also a GC language. Where did Java fail?
