Freighters aren’t difficult to get now…

You gotta assume paradox is fully capable of breaking your game saves without mods involved though!

Generally agree, but your idea that native games are safer than websites is backwards. Browsers are basically hardened sandboxes for running untrusted code. Even though steam does a good job of detecting and taking down malware it’s still downloading executables that run with full access to your system (unless you run steam in a sandbox of some kind). Playing games in a browser is no less safe than loading any other website.
