First off, download the game in Steam.
When the "Bloodline 2" is installed open the Software Center and search for ProtonUp-qt and install it.
In ProtonUp click "Add Version" and pick GE-Proton10-21.
After that click "Show Game List" and find Bloodline 2. Under compatible choose: GE-Proton10-21.
Now you're set to be a true vampire 
Do let us know how it is. I played the original 20 years ago and it had tons of potential it didn't get to fully realize. With this at mixed reviews, an absolutely tortured development cycle, and Paradox's awful recent track record I'm wary.
I'm actually having a blast, this is fun! But I normally don't play such games, as I more into strategy and turn based RPG. And this is my first time into action RPG.
So I don't know if my little review here counts.
Then you should get familiar with Dungeon Soup it's in the repositories. It's great!
Disney+ has a new show for kids, called Vamperina, and its got vampire's in it, as well as, vanhelsing's, and humans. It does an interesting thing of mixing all three together in a public arts school. Of course, no blood and gore, Disney does not go full Hulu on its young viewers.
BTW, Disney got in trouble a while back, when the accounts were completely open, and kids were getting access to content more suitable for 18+. Thats why they forced Disney+ account owners to set a password. BTW, I got a notice recently from Disney, that they will soon be fully integrating Hulu, because they purchased Hulu.
But yeah, I've seen some totally rated R vampire movies before, like the Blade series. Anyone who remembers the blood disco shower seen, totally knows those movies weren't for kids. I tell you what, they did Wristler wrong in that series, then they brought on that punk kid, I knew the movies were going off the deep end then for sure.
Dungeon Crawl Stone Soup? I'm familiar; it's a proper roguelike. I've got a lot of disdain for the vastly overbroad use of the term as someone old enough to have hung out on rec.games.roguelike.nethack back in the Usenet days, but DCSS deserves the term. I played it for a while, but couldn't resist playing as a cat, and eventually the mental image of all the dead kitties I was leaving behind kind of got to me. <_<
