I saw these adaptations of the Lion Rampant rules when they were first created and thought it sounded like my kind of project. Unfortunately most of the ranges in metal were a bit too expensive for my pocket at the time. I reckon 1 box of Conquistadors and 3 of Aztecs will now make this a reality. I'm really looking forward to these figures.
