I've been wanting to try Godot since it's really cool to have an engine that's open source (which is important to me since I want to feel like I'm actually in control of the tools I use) but I haven't had a project that feels like it calls for it just yet. If I'm just making a 2D sprite game I'll generally want my game logic to be in C or C++ and not tied to an engine, so I can port it to whatever platform I want without much trouble, so it would have to be a game that wouldn't matter for. So I've been thinking I'd explore it when I finally try something 3D.
I did follow some tutorials. The overall setup of everything seemed interesting, though it definitely did look like something I'd have to get used to, because it's a very different way of thinking about game dev. I also tried making a dev tool in it at one point, and it turns out Godot is actually really good for easily making GUI programs in, though I didn't end up going very far because I realized that if I made the tool there'd be a net time loss, compared to just doing the thing the tool was going to do by hand.
Petal Crash 2 uses Godot and I've been able to have a peek into the development of a Godot game that way.
