Where each one falls short

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

Bevy

  • Rust only, so it assumes a language most game teams do not already use
  • No visual editor of the kind Unity or Godot provide, so scenes and logic are written in code
  • Built around ECS, which is a different mental model from the scene-graph engines most developers come from

FMOD

Nothing recorded yet. See the FMOD review.
