Contents.
Third edition.
"GURPS Magic" is a supplement of magic rules for use in fantasy milieus, an expansion and replacement of the rules in 1st edition "GURPS Fantasy", entirely revised for use with the "GURPS" 3rd edition. The book is very detailed, and the spell rules enable the player to custom-design a character's magical abilities, although this can take a fair amount of time and effort. The book includes an extensive spell list.
Fourth edition.
This 240-page hardcover book with full color illustrations covers the third edition source books GURPS Magic and GURPS Grimoire and adds additional material. It is the latest version of GURPS Magic.
Publication history.
"GURPS Magic" was originally written by Steve Jackson with Marc Janssen, Walter Milliken, Steffan O'Sullivan, W. Dow Rieder, Brett Slocum, and Daniel U. Thibault, with a cover by Guy Burchak, and was first published by Steve Jackson Games in 1989 as a 112-page book.
Reception.
In the June 1989 edition of "Games International" (Issue 6), James Wallis thought the book wasn't needed by those who already had the previously published "GURPS Fantasy". He gave it an average rating of 3 out of 5, saying, "If you use "GURPS Fantasy" already and are happy with it, stick with it. If you missed it the first time around, "GURPS Magic" is a worthwhile buy."
In the July 1989 edition of "Dragon" (Issue #147), Ken Rolston was impressed, commenting, "The "GURPS Magic" game is an excellent supplement for the "GURPS" system, an effective expansion of the game's original fantasy magic rules with added features and wise campaign-design guidance. As a FRPG magic supplement, it boasts exceptional virtues in systems and conceptions. As a generic supplement, however, it lacks the distinctive charm and atmosphere of a specific fantasy campaign setting. As a source book for enriching the magical elements in your FRPG campaign, it is useful—perhaps inspirational—regardless of the system you use."
Five years later, in the June 1994 edition of "Dragon" (Issue #206), Rick Swan gave high marks to the second edition, saying "[Steve] Jackson made a few design choices that may not be to everyone's liking. In order to pack in as many spells as possible, he occasionally skimps on descriptions. [...] Nor does he dictate how much detail the spell provides. The magical-item rules make it difficult to create off-the-wall oddities favored by "AD&D" mages, like the "portable hole" and "bag of beans". Also, the small amount of new material - a system for limiting the power of wizards, flow charts that show the prerequisites for spells from all colleges - barely justifies a second edition; owners of the first edition can put their money away. These are nitpicks though, irrelevant to the overall impact. A dazzling performance by a virtuoso designer, "GURPS Magic" is a knock-out." 
In the September 1994 edition of "White Wolf" (Issue #49), David L. Pulver gave the second edition of "GURPS Magic" a 4 out of 5 overall, commenting, "If you already have the first edition of "GURPS Magic", there's no need to buy this one unless your copy is worn out. If you don't have it, and you want to use magic in "GURPS", the material offered here is a vast improvement over the skeletal rules of the "Basic Set"."
