I’ve always been intrigued by the idea of running a MechWarrior campaign and using BattleTech for in-game mech battles. The fact that the PCs are involved would put a different spin on the wargame aspect (and vice versa), and it sounds like fun.
There are other RPG lines that also have (or had) wargames associated with them, including D&D and the D&D miniatures game, and it might also be possible to adapt unrelated wargames to some RPGs (or vice versa), even if neither the RPG or the wargame is designed for this purpose. Either way, I’m curious what this is like.
Have you run an RPG campaign that dipped into (or centered around) wargame-based combat? What’s it like? What unique GMing challenges does it present?
