You typically don't get "ownership rights" when you purchase a game on Steam. You'll typically be purchasing a licence to play the game, which could be taken away at any point. Some Steam games don't include DRM after installation, and you'll truly own those games after downloading them. (you can search for a game here, and find the DRM used) I'd recommend avoiding purchasing games on Steam whenever DRM is included if you want to own the game you'd buy, there are a lot of online stores that sell games without DRM.
Is there something I'd need to do to have it recognize the card?
I can't find anything that isn't only for Windows.
I'd prefer to get a VPN to avoid the risk of my internet getting shut down, but I'm not aware of what the options for Linux are. I figured this would be a good place to ask.
That's what I'd go with it. Came here to comment it, but I was beaten to it. There are so many great ways to play through it, as the modding community has made so much amazing stuff over the years.
The title says it all, I'd like to switch my operating system and preserve most of my files. Any other info I should know before the move would be nice as well.
They removed the repo, but many people have archived it.
Do I see Dusk? I love Dusk! Go buy this right now. If you're concerned about digital rights management, don't be. New Blood never adds it to their games.
