> Just to make sure, are their any money based licenses around Godot?
Nope! The engine is completely free and open source, following a FOSS philosophy. There is a Patreon for donations, and users who donate get credits they can use to vote on new features and documentation in monthly polls. Godot Engine is managed by the Software Freedom Conservancy, a non-profit dedicated to free and open source software, so you can rest easy knowing that there are no commercial incentives behind its development. The developers' are purely devoted to building the best engine possible for the community.
