> Godot is only the best open source engine because Bevy is not ready for production

I would argue that even if Bevy was ready for production it would not really compete with Godot.

Godot's performance is plenty for the vast majority of small to medium games. Plus they're starting to work on features like texture streaming for bigger games. It also has an editor which is a big plus for most teams.

Bevy would be objectively better for expensive CPU simulation stuff but realistically what percentage of games need that? Maybe 1%?

For Bevy to catch up on the indie game scene it needs an editor plus a scripting language and/or something like Unreal Blueprints. If it only wants to target the hardcore Rust dev that does everything by code it will never go mainstream.
