Dark Souls™: The Board Game from SFG implemented the original game's game mechanics. One notable thing missing is parrying, which to tell the truth I didn't use at all, but would still like to have as an option in the board game.
I love the Dark Souls series, finished all three of them on PC and also Demon's Souls, which is the predecessor on the PS3. I didn't yet had the pleasure of trying Bloodborne or Sekiro yet, but I'll get there sometime too. These games invented a lot of great gameplay mechanics and I was wondering if some of these could be applied to tabletop RPGs.
