Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

jMonkeyEngine

  • jMonkeyEngine is a code-first Java library with no bundled editor; the engine itself ships no scene editor

  • Projects must be written in Java and wired up through Gradle, Maven or a hand-rolled build
  • Choosing the DIY route means providing your own build, source layout, editor, runtime packaging and workflow
  • Support runs through community Discussions and Discord rather than a vendor channel

Phaser

  • The Phaser framework is open source but Phaser Editor is a commercial product at $12 per month
  • Phaser Editor stops working when the licence expires
  • No free trial of Phaser Editor is offered
  • AI tools in the free Phaser suite require purchasing credits
