I know this is the piracy community, but why not just buy it? It’s like $15 lol
If you’re planning on modding the game (which isn’t an easy task on Linux, I’ve been using Arch for a decade and it was a nightmare getting it to work through MO2), be aware that some mods (usually only SKSE mods) flat out won’t work with a cracked version of the game, the authors wrote checks in the code I’m guessing to look for specific strings or versions. Then there’s the issue of multiple exe versions and some mods only work with specific versions.
