Hi Vic -
I've been lurking these boards since around when Cults came out, but I wanted to post for a few reasons. First, to tell you what a great game you've made and how much I'm looking forward to Tip of the Spear. Secondly, I've been reading the posts in here about ideas for fighting the uberstacks and I've come up with an one that might work for the TBA abilities you are going to be introducing.
It would be a guerilla ability that you could attach to infantry, and would give that army the possibility of a guerilla attack, which would be 2 dice + total number of units in the army being attacked, meaning against a general with a command rate of 8 and a full army, they would get a 10 die attack. The thinking is it would be easier to find and hit a target in a large army on the move than a small one. I think the target should be a unit the player can choose, not just random, and a successful attack could do damage to the unit plus give it negative modifiers either for the next round, or indefinitely. This would soften up an uberstack so a medium strength army could then go toe-to-toe with it.
After the guerilla attack, the guerilla army would make a roll against the recce of the army it attacked, and if it beat the recce, it would immediately withdraw. Failing the roll would lead straight into combat with the army it just attacked, because the guerilla army was spotted. I've been going back and forth on also including something like 'trickster' in the guerilla skill, too, so even if the unit is spotted, it can still make an escape. Maybe the guerilla unit could withdraw before the first round, but there won't be negative modifiers to the attacking roll, so it's more likely that the guerilla unit will take some damage or be destroyed if the recce roll succeeds?
I also think there should be penalties if you are moving multiple guerilla units within the same army, say bonuses to recce rolls or the subtraction of defensive dice in retreat rolls, with the thinking being that it would be easier to spot the larger army as it tried to escape.
So that's the idea. Obviously the inspiration for it came from ideas and comments other people on these boards have had, but I don't think I read any where the potential attack against the stack is being determined by its size. Not sure how workable it would be, but I wanted to throw it out there.
Again, thanks for making such a fantastic game, and for all the work you are doing to keeping adding even more. Now it's time to get back to Toxic Bog's mutant scenario 8. So many mountain bases to build!
Don't blame me, I voted for Kodos.
