Before the Unity suicide, I doubt it had 10% either. And you know, making games takes time, so in terms of released games, we might still not see an uptick.

But I do think newly developed, particularly indie titles will go beyond those 10%, and maybe even quite easily so.
There’s not many statistics out there, so here’s some horribly biased ones: https://gamefromscratch.com/godot-popularity-at-gmtk-jam-2024-explodes/

This is from a gamejam held by a particular YouTube channel. That YouTube channel has an ongoing series about making a Unity game, nothing about Godot yet.
But it is a gamejam, where people sit down for just a weekend to make a game, so people will be much more willing to try a new engine out. Although they’ll typically have some prior experience, since you don’t want to spend the whole gamejam learning an engine.

But yeah, those caveats notwithstanding, that still is a significant growth for Godot.

Doublechecked it, and it’s 4% based on steamdb for 2023, and 5% for 2024 That’s of course counting only these three.

Steam released 14500 games in 2023 (all engines).

Unreal on steam was 2400

Unity was 7400

Godot 400
