Honestly, the small and super friendly community of Defold is one of it’s great bonus strengths. Focusing on helping serious devs ship games is such a wise paradigm, IMO. Keeps things optimized and lightweight, just like the engine.
In contrast, looking at something like Godot, their Discord and forum are inundated with the same questions over and over again from what I call ‘game tourists’ which makes communication with the actual engine devs very reduced 
(Whereas in Defold the engine devs answer questions and discuss concepts with game devs using Defold with a very impressive regularity!)
