Recources? I don't think any of them have resources. And yes, I have thought about that last strategy lol. But I would probably hold myself back from doing that, at least in most circumstances.
By the way, wouldn't be more realistic if some units could actually enter provinces with low infra?
I mean, few areas are really unpassable for a barefeeted unit, especially if they're grouped with an ENG unit.
I would divide it in three levels:
Level 1 (infra 1-3): accessible only by feet units (INF, MTN, etc.) with ENG giving bonuses and other attached units (ART, AC, etc.) removing the possibility.
Level 2 (infra 4-6): accessible even by by mobile units (ARM, MEC, MOT) but only if they have ENG attached with them.
Level 3 (infra 7-10): accessible to everybody.
Anybody agrees?
