I have! Beat Dust many years ago, and played a good bit of Frost. Now I’m more into perfectly fixing, tweaking, and expanding NV and TTW.
Is it worth adding a windows install for?
nah, TTW is just an extra area to acquire XP and bonuses to refine your build, it doesn’t really add much to a playthrough extra modded content for base FNV wouldn’t. unless you’re really down for those mods with NV-TTW interactivity
Eh, maybe if you do the install in Windows then transfer it to Linux, but that’s a lot of effort, sadly
