Pretty much echoing what everyone else has said, but it really is the perfect hobbyist engine! GDScript for those familiar with python or just plain new to programming, with C# available to those migrating from unity (like me); open-source & free; the fact that it’s all self-contained is nice; extremely lightweight, both on storage and memory; and, for me, the fact that it’s got the foundation behind it, pushing out new features at a really quick pace.
