I am running a fantasy FUDGE game and I needed some sort of magic system quick. Fudge Magic not only has the 50 spells, but also offers comprehensive descriptions on over a dozen types of magic. I used these as a basis for my FUDGE game. Supplementing with the four by five FUDGE magic system I was able to run a campaign with magic rather easily.
The one thing I did not like was that the PDF was secured and prevented copying and pasting. As I was pulling from various sources to build my own game (for personal use, not commercial resale), I found this irritating and had to find a work-around. That being said, I understand the publisher's need to protect their work.
Regardless, this is well worth $3.00. For the price and content, this is a fantastic product. I hope Seraphim Guard releases future FUDGE products and/or supplements. I definitely look forward to more of their work.
