For more information on Titan see my Titan Home Page.
Titan is a multiplayer (2-6) boardgame produced by The Avalon Hill Game Company (owned by Hasbro) and is currently out of print. It is billed as a Fantasy Monster Slugathon.
The game consists of two levels of play. Players move legions on one large map recruiting minions to fight with. When two opposing legions meet on this board the battle is fought out on a different board representing the type of terrain the legions were in on the main board. Each player is represented by a special character (a Titan). When that character is killed the player is eliminated. Play continues until only one or zero players are left.
A seperate question is "Will I like Titan?" for which the answer is maybe, maybe not.
