tabletop game by Gamelab, published 2004 by LEGO

LEGO asked Gamelab to design a game for the X-Pod product line - a series of jar-like containers, each with a small number of color-coordinated, themed LEGO bricks. The result was X-Pod Playoff, a game where players strategically build and then deploy LEGO creations.

Like a game of Chess where you create your own pieces, Playoff players used recipe cards to build units and then deploy them strategically on a map. Each construction had different rules for movement, attack, and defense. As they were damaged, they lost bricks and their abilities declined - but you could use the castoff pieces to build new units. 

An extremely fun design that supported surprisingly deep expert play. A sequel, X-Pod Playoff 2, doubled the number of units and was released a year later.
