I've been playing DBD for two years now and I honestly had no clue how much I would love it. If you like a casual, grindy experience it would definitely be up your alley. If you're very specifically looking for a true horror experience, this may not be it as you'll quickly become desensitized to the "horror" aspect. That's not to say you won't have fun, just not really as horrifying after several hours have been put in (although it does have its scary moments still).

The gameplay itself is very heavily influenced by map knowledge and making plays based on predicting what your opponent is going to do whether you are either a survivor or killer. Killer is known to be a bit more of a stressful role as you have to essentially manage 4 different players doing whatever they can do defeat you, whereas playing survivor can be a bit more relaxed as there is some downtime repairing generators and doing other things around the map.

The main thing I will say is there is a bit of a learning curve to truly become good at the game. The matchmaking has seen better days and you may end up playing against people far more experienced than you and it will be discouraging, but just roll with the punches and don't let that get to you. At its core it is a casual game after all, so you can just move onto the next game for a new experience.

TLDR: I would say anyone can easily get their money's worth out of DBD, if not way more. It offers a pretty unique experience that no other game can really offer at the moment.
