Technically the same game as they take place in the same universe, however Iron Kingdoms is a d20 Pen and Paper RPG, and War Machine is played with miniatures, much k**e Warhammer, meaning it can get pricey.

Regardless, I figured I would bring this to the attention of our air city's fine citizens.
