When it comes to TV shows becoming video games or movies they tend to not do well. Except Supernatural show has been out more than 12 seasons, has a big major fan base and I believe it would be a awesome open world single player and even a online co-op game. We could play as Sam or Dean in an open world doing major cases like in the show and/or make our own character and help them out and be able to go off on our own hunts, make deals with demons and do the family business and mess stuff up or even choose to be a supernatural creature and get hunted by hunters.

and idea for multiplayer would be 2 players as hunters have one hour (game time) figure out which supernatural creature is messing with the town and another person is that creature (of course each creature would have different abilities). There are tons of game companies out there, but the one company that comes to my mind when it comes to amazing open world story driven games is Rockstar games. The owners of the Grand Theft Auto series and RedDead Redemption which both are considered amazing open world story driven games.

I believe this would be an awesome open world game and I also believe the creators of the show would help out with story and maybe even carry it over from the show (whenever they do come up with an ending if they do). If this happens not only will there be an awesome story driven open world game that is based on a great show RockStar will prove that story driven games are still amazing.

If this doesn't happen then Rockstar would be missing out on a gold mine and players will be stuck with micro transactions loot box online only games and single player games will soon be no more.
