Spending the whole year gaming exclusively on Linux is.

Don’t know because I don’t use those, you will have to try and see.

Keep an eye on the NVK project.

Technically you could mod these games on Linux but it was a bit wonky. So I preferred to play these on Windows with MO2.

Then I started using Steam Tinker Launch to setup and run MO2 on Linux and thus stopped using Windows.

However STL does not seem to be getting updates these days so I now use this for modding Skyrim, Fallout, etc: https://github.com/rockerbacon/modorganizer2-linux-installer

Edit: Nexus mods are also working on a cross-platform app for modding, though its still in alpha. Currently only a few games are supported with support for more coming soon.

Steam Deck is not available in my country :/

I still have Windows but haven’t logged in in over a year. I use Bottles for all non-Steam apps.
