Hey look, another card game! With Vampires! VEmpire - The Kings of Darkness [Steam] will release in October and they will have day-1 Linux support.
The official trailer doesn't really give a feel for things, so here's some raw gameplay the developer put up:
The game will have single-player, the ability to play against a friend and also be matched against someone if you're feeling competitive.
I'm actually a big fan of card games, so I'm quite interested to see what it's like when it's released. It will go into Early Access first, so the developer can act on feedback.
It seems the single player against AI will also eventually include a story mode, so you can learn the story behind the characters.
Thanks for the tip, Craig!
