There is also a further series of books, of emphatically female fighter-types, under the collective title of "Queen's Blade", published from late 2005 by "Hobby Japan". With more than 20 books the books were generally new illustrations for existing combat matrices, rather than "new" characters (although at least one "doujin" has utilised what appears to be a "new matrix"). As of December 2007 a second series, "Queen's Gate", was introduced, featuring characters from Japanese visual media, and in October 2008 Hobby Japan announced four further characters in a sub-set of the original series ("Queen's Blade Rebellion"). Jill Leonardi, the daughter of the original game designer Alfred Leonardi, has been designing new character matrices for the "Queen's Blade" series since 2010. In 2012, Jill founded "Firelight Game Company" with partner Todd Broadbent with plans to release new characters under the brand of "Legend's Gauntlet" in a new but fully compatible format. The Leonardi move-matrix system has also been "borrowed" by other publishers, notably BattleBooks and Games Workshop as the engine to drive their own combat picture book games. Chris Hunter reviewed "Lost Worlds" for "Imagine" magazine, and stated that "All in all, Lost Worlds is a quick, fun system, if you can ignore its shortcomings [...] but I cannot imagine myself playing much more than a quick battle or two while waiting to start an evening's role-playing." In the May 1984 edition of "Dragon" (Issue 85), Ken Rolston found the game entertaining and fast, but expensive and with limited replayability. "The "Lost World" game system is an entertaining, superbly produced minor diversion. It earns the highest marks in playability, time and effort to learn, presentation, originality, system quality, and dramatic effect, but its applications are limited and closed-ended, and the cost is perhaps a little steep for a quick thrill. It is certainly worth playing, but less likely to stimulate sustained interest, especially when compared with other similarly priced games." In the April 1996 edition of "Arcane" (Issue 5), Cliff Ramshaw was not overly impressed with the Flying Buffalo version of "Lost Worlds", commenting "Although "Lost Worlds" is fun, there isn't a great deal of longevity in the format. It's not going to keep you occupied for hours at a time. On the other hand, it represents a great means of resolving certain combat situations in your RPG system of choice."
