Not for the TV series no, but the game adaptation of the TV series, or possible book. Superannuation discovered the trademark made by the TV network, for which this could possibly be its first real debut into the videogame market.
For those unaware; True Blood is a show about a young psychic woman in a small Louisianan town, and her romantic relationship with the 150 year old vampire named Bill. More than that though the series tackles the question of what would happen if vampires ever “came out of the coffin”, as they do in the show. Despite the description the show features quite a bit of action revolving around the paranormal, it might just work nicely as a game.
HBO hasn’t confirmed or denied any plans on making this more than just a trademark.
