The way my group and I roleplay, there is little point in trying to predict what kind of landscape is going to see tactical combat. I own all of the Monolith stuff so far (none of the Modiphius tiles). The players choose Monolith minis to represent their characters, but I prefer abstract beads to represent all NPCs. I have difficulty predicting what sort of mini, exactly, might be required, and the minis seldom are accurate representations of what I’m describing, as a GM.
We use a wipe away mat of squares for the tactical scenarios. I love the zone system. I always try to innovate interesting elements to the stage.
