As someone who plays games, if I see witchcraft in terms of pentagrams, the devil...etc. I won't touch it. Or I will quit the game if I find it later on. I still may play game that has fictional magic. Not if it calls it spells or really seems to be more along the lines of witchcraft itself.
A good example of this is Thor has "magic" to humans. But he says its actually science. As in they are more advanced and its not actual magic. Just as if you brought a smartphone to someone from the 1900s, they would think you were a witch.
But it is a very thin line on if something is acceptable or not. I loved Lord of the Rings for example. But am 100% against Harry Potter. Some tell me "So you are a hypocrite! LOTR has a wizard and magic too!". And technically they are not wrong. However in my mind LOTR is fictional magic, Harry Potter is based on real witchcraft, just with a more fantastical view of it.
I find the subject to be hard to because you got super strict christians who are against any forms of magic because they think its all witchcraft. And then you got some who accept any form of magic, even if witchcraft based because "It's not real!" or "It won't harm anyone!".
Which I should add is another good point. I love LOTR but I don't go around with a staff pretending to make light appear from a staff. I don't pretend I can talk to animals for a ride. I don't act like I am Gandalf. Where on the other hand MANY know Harry Potter (and companies) spells by heart, what to say, how to move about the wand...etc.
If the subject you are talking about has you wanting to be part of it, then you should rethink the subject.
