And with any luck some sort of justification of how in the last game Swordsmen could take out helicopter gunships ??
Ever hear of "Veterin Spearmen on a hill beats tank"?
Spearmen: Str 3
Tank: Str 32
Spearmen gets the following (assumes on a hill with fort; fortified for at least 3 turns):
3x Bonus against calvary [STR = 9]
+50% defense modifier for fotifying for 3 turns [STR = 13.5]
+50% defense for being on fort [STR = 20.25]
+33% hills defense [STR = 27]
+20% STR bonus for veteriny [STR = 32.4]/40% STR bonus for elite [STR = 37.8]
Plus others I can't remember right now; stacking traits add up quickly [and the order makes a big difference, I and fail to recall in what order STR is stacked; I also forgot the exact bonus for forts, so I assumed 50%. I play a lot of mods now, so other values may be off, but you get the idea...]
The best way to handle this [and one mod for Civ4 did exactly this] is attach an "Age" to each unit [Ancient, Bronze, Iron, etc]. When facing a later edge unit, the attacker gains a massive bonus [50% for one age, 100% for two ages, 200% for three ages, etc]. So while an old unit would have a chance against a unit one age later, the Spearmen v tank will finally be setteled.
