One of the great things about a simple, elegant rules system like Mobile Frame Zero is that it lends itself so well to other applications. I’ve seen people talking about using it for fantasy battles a la Lord of the Rings; spaceship combat; modern military combat. One thing I haven’t seen, however, it using it for naval warfare.
This line of thinking has been inspired by a number of wonderful microscale Lego ships such as those scattered about this article. Most of these aren’t much bigger – or more brick intensive – than your average MFZ frame. Ships also lend themselves to the attachment based system of MFZ: close in defence systems (melee weapons), gun turrets (direct fire weapons), missile launchers (artillery weapons), radar systems (spotting), hydrofoils (movement), and so on.
