Is there something that Godot -->CAN'T<-- do?

I tried (briefly) Unity and Unreal, but settled with Godot because of how much I liked the workflow.

But I'm wondering, is there something that Godot **CAN'T** do? I'm more interested in Indie and AA game development, but I'd appreciate feedback/knowledge about AAA too!

I ask because I'm impressed by how much game engines can do by themselves, it's a nice, nice fresh air, compared to web dev, where you....... y'know what, I'm not gonna rant for 500 lines. Anyways, so far I didn't have to use an outside resource, so I wonder what are the limitations of Godot compared to the other popular Engines?

(Unity, Unreal, RPGMaker, GameMaker, etc...) ?
