Forts with 0 cost for the Romans are already in version 2.0. I forgot to add it in the updates list. Nevertheless, here is how you can do both things:
1. Making forts cost 0:
Code:
Open the file 77bc\data\descr_cultures.txt
Look for "fort"
Set roman fort cost to 0 like this:
fort data/models_strat/residences/roman_fort.CAS, fort_roman
fort_cost 0
2. Changing the legions script. This is a bit more complicated . Open the file: 77bc\data\scripts\show_me\Marcus_Camillus_4TPY.txt
Look for "SPECIAL LEGION FEATURE"
You will find several entries like this:
Code:
monitor_event UnitTrained FactionType romans_brutii
and TrainedUnitCategory cavalry
and SettlementName Rome
spawn_army
faction romans_brutii
character Gaius, general, command 5, influence 5, management 1, subterfuge 1, age 36, , x 95, y 73
unit KA sertoriani first cohort i, exp 0 armour 0 weapon_lvl 0
unit KA sertoriani legionary, exp 0 armour 0 weapon_lvl 0
unit KA sertoriani legionary, exp 0 armour 0 weapon_lvl 0
unit KA sertoriani legionary, exp 0 armour 0 weapon_lvl 0
unit KA sertoriani legionary, exp 0 armour 0 weapon_lvl 0
unit KA sertoriani legionary, exp 0 armour 0 weapon_lvl 0
unit KA sertoriani legionary, exp 0 armour 0 weapon_lvl 0
end
console_command add_population Rome -1000
console_command add_money romans_brutii, -5000
end_monitor
Just add three more "unit ...., exp 0 armour 0 weapon_lvl 0" to each of the entries and rise the cost here: console_command add_money romans_brutii, -5000
Hope this helps
