Only the ECS.

I fail to see how that's particularly relevant, considering that this discussion started with the implication that ECS specifically is a neat fad that Bevy users will eventually get bored of.

And again, I am not sure what exactly people are expecting of a game engine that started development in 2019. Development of Tiny Glade itself started less than three years after Bevy's first commit, which was an obvious factor in Pounce Light building a custom renderer.

It's relevant because the post I replied to is misleading on its own.

How is it misleading? Even Unity and Unreal games often have parts of the engine modified or replaced, e.g. swapping built-in audio for fmod/wwise or built-in physics for something in-house. Pounce Light has discussed the fact that it's primarily the renderer that they replaced[0], and they are not the first, nor will they be the last studio to use a custom renderer.

If your criteria for "made with Bevy" is "every single system in the game must be from Bevy", then sure, you won't find a single Bevy game in existence. But you will also find a lot fewer Unity and Unreal games than you think.
