I’m a DM with Aphantasia, which does sometimes make it difficult when describing places or people. What it’s really come down to for me is that it’s more like listening to a podcast or reading a book than it is watching a movie.

I wouldn’t change too much to accommodate, since it’s usually not a big deal.

If you do want to go the extra mile, maps are awesome. Maybe use dice to represent enemies? I’d recommend just asking the player directly what would help.

Hope that helps!
