Lost Worlds is a "combat picture book game" designed by Alfred Leonardi and originally published in 1983 by Nova Game Designs. The game has had many publishers, including Chessex, Emithill, Flying Buffalo and Greysea. In 1984, Lost Worlds won the Charles Roberts/Origins Award for Best Fantasy Boardgame of 1983.
Advance publication notices imply that a minor resurgence in published books may be occurring, with 5 new titles in 2004, a further 2 published in June 2005 (both with photo illustrations rather than graphics) and a further 4 books, of emphatically female fighter-types, published in late 2005 by HobbyJapan. These 4 books, on publication, proved to be new illustrations to existing combat matrices, rather than "new" characters, but there are now 2 further character books being advertised (although these may also be hentai "retreads" of original books).
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.
Gameplay
Each player chooses a character from those available. They take the character sheet for that character and give the character's "visual combat book" to their opponent. The character sheet lists all the combat moves which the character can make. The combat book lists the effects of the attacks in tables.
