Abyss
It's lonely in the deep
I've finished it but I was replaying a month ago or so. It really is good. I have yet to find a vampire-centered game or RP that scratches the itch this game has left in me lmfao.
Vampyr is definitely one of those games that hits all the tropes I love for traditional vampires, though I wish we got to see/interact a bit more with other vampires. The Ascalon Club was cool, but I was disappointed they didn't have their own web/community thing going on.
I've heard that Vampire The Masquerade is really good if you're looking for another vampire game. It's based on an old table top RPG and there's currently a new game in the works that looks promising.
