Wow the person that wrote this article clearly does not understand how open-source or piracy works. Using a closed-source game engine is not a factor in mitigating piracy, at all. Using an open-source game engine does not make Slay the Spire 2 open-source “by proxy” or otherwise.

This is mostly true, but it depends on the license. Godot is MIT so they’re fine.

It usually depends if you link against/embed their code. For example if the library is GPL (LGPL is usually fine) then your game code may be liable to become GPL as well.

The moral of the story is to always check the license of your dependencies before distribution.

Or just use malus.sh

(I say this out of horror that such a thing exists)
