I think they should put demons in every game, actually. Like have Jack Frost show up in Animal Crossing and freeze your entire island that would be rad

These are all the games that I felt like including on this list that have demons in them (it does not count if the term demon or some equivalent isn't used). It should be noted that not all of these games are actually, like, good. Having demons may automatically make a game way better, but it can’t save a game that already sucks. Shin Megami Tensei is definitely the biggest and possibly the best demon video game series; in fact, every demon game is just a reskinned Shin Megami Tensei if you really think about it.
