So if people like the abilities for the Military Base, and only the relative cost is in question that seems an easy fix to me. Maybe just drop it to 12 ipcs?
I do worry that anything too low might be overpowered. The whole game comes down to pushing hitpoints. So allowing players to introduce 3 more hitpoints anywhere on the map is pretty significant. It’s 3 per turn once purchased, so that can add up pretty quickly, in some regions. Especially if, as with all the other bases, they can be stacked onto a territory with a Minor IC. We also don’t want it to totally undercut the transport in value/significance.
My suggestion of 15 ipcs was just for parity with the other OOB bases. And to prevent an all out spam (esp. by Japan/Germany). Though I admit 15 seems high for all bases, I would have preferred 12 as the baseline cost.
:-D
But if you want you could have an add tech option “cheap bases” that reduces the cost of all bases by some set amount, like 3 ipcs cheaper to build. (This would drop the cost of the AB/NB from 15 to 12, and drop the MB from 12 to 9.)
Or an add tech option “auto-destroy bases” that removes them on conquest. To help prevent a spam.
Or maybe come up with a secondary ability that somehow makes the 15 ipc price tag for the Military Base easier to swallow? The other two base types each have 2 abilities. Though I’m struggling right now to think of what else a Military Base might do. We’d need an ability that basically already exists, since new abilities are pretty hard to introduce into tripleA. Though honestly 3 hitpoints is pretty powerful all by itself, I don’t know that it really needs a second ability to be compelling.
I’m not hardline though. I suppose I’d rather have it too cheap, than too expensive, since I’m interested in how it might be used to rebalance certain regions of the map for staging.
Just imagining how the Med and North Africa might look, or the Mid East, or the PTO islands, or the Soviet Far East etc. Even the theaters that are currently the most active, might become more interesting. There are a lot more TTs on the Eastern Front at a value of 0/1 than 2. A territory like Normandy or Southern France might be more interesting as Allies if you had the option to add 3 more hitpoints (each turn) beyond what the Minor can produce, with an MB purchase to support it.
Clearly Japan would be dangerous on the mainland, but the Allies would have alternative ways to support the India IC with hitpoints, since there are more viable territories for MBs in the area than there are for Minor Factories (and the MB buy could reinforce a Minor Factory purchase too, bringing a territory like Persia up from 3 to 6 hitpoints per turn.) I see a lot of options there. I think the US has the most to gain from this idea though, since they have the longest distances to cross, the fewest number of viable locations for Minor factories, and the greatest logisitcal challenge in drawing up reinforcements. So I think they would be able to really utilize an MB, which also seems somehow fitting.
