Old late 70's, early 80's fantasy animated movie.D&D based?
I would like to find the name to this movie. All that I remember of it is that it starts in a bookstore, a young man, with glasses does or purchases something there that ends up taking him to a fantasy land. If I remember right, it has a D&D feel to it, as though he was playing the game and ended up going there. But of course he meets a girl, he ends up going home without the girl and is sad but when he gets to the bookstore, she's there waiting for him in modern clothing. That's all I remember of it, the beginning and the end. If anyone knows what I'm talking about, help would be greatly appreciated. Thank you.
