Keeping it short but sweet, my primary group have discussed the notion of a campaign in which we take on the role of a super heavy armoured regiment piloting a Baneblade.
This led me on to a crazy idea for another game I'll be running for another group on a Post apocalyptic world. Enter a regiment of guardsmen riding something similar in scope to a Squiggoth or Middle-Earth Mumakil.
Now these are concepts that I would go so far as to describe as "cursed with awesome". They're things I'm sure many would love to play but...How to keep them interesting? The tank campaign problem on a much larger scale.
We managed to make an interesting concept for an artillery regiment. I'll be damned if this beats us.
