And now for something completely different.
There used to be an old Collectible Action Figure/Card Game called Z-G designed by Mark Rein-Hagen. This is what the action figures looked like.
Now, I hadn't thought about it until the other day -- because someone brought it up on a forum I frequent -- but these figures might work for a larger scale game of MFZ. I actually own one each of the Green one and the Blue one and I'm kinda intrigued by the thought of using them at some point.
Noble Knight still has the Green one in stock, and I've heard of other sources for the figures.
