By proxy (to Godot), Slay the Spire 2 is also open-source.

Using an open source game engine doesn't necessarily make your game open source. Even if you could get the source code onto your computer that doesn't mean you can redistribute it legally.

Taking a dev saying they're not bothered about piracy and hope people can learn from the source code as a legal "OK" is like building a house on sand. An actual open source license is not a comparable as a foundation to actually build upon it.

Who wrote this garbage? This is filled with lies.

Your game engine has no bearing on piracy. That's the job of the store front, not the engine.

And using an open source engine does not make your game open source.

WTF

If Godot hasn't fixed this, then when you release your game on Android you're also exposing your source code to the world: https://old.reddit.com/r/godot/comments/198garj/psa_all_godot_4_apps_you_upload_to_google_play/

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.
