hello Achi and DJGspinNhitz,
Achi I could use your save game and the log files (Database and Lua.log).
I will look into the culture and gold issue this week, at least this is something that I can solve really quick. Next will be the upgrade costs, it will take longer : I have to look into the game mechanics to see how those are calculated.
About the units range :
Archer with 1 : I did that some time ago but it did not reflect the ability for archers to shoot above a shield of infantry/cavalry troops (and this makes more sense than the early canons shooting above the troops to be honest
)
Is there a reason that cities keep using rocks about cannon are researched?
The animation for the cities is bound to the Era not to a specific tech.
Can city range be increased with same premise of weapons?
It's probably doable, I wil keep it in mind and have a look in it.
But on the other hand : the ability for cities to fire makes sense until the medieval era : at this time catapults and other "heavy" weapons were served by women to defend the city. This would free the
men to fight as troops. Since the Renaissance cities are either defended by troops or defenseless.
The ability for the cities to fire can be seen as a militia, but to have heavy weapons with long range you need the regular soldiers.
With flight add Air Raid Shelter which reduces damage from bombers by 5%.
Research integrated air defense increases damage or interception to incoming aircraft by 5%. (National Wonder with Radar) Add radar to all cities and it opens Radar UNit makes city and nearby AA guns 5% more effective.
Nice idea, I put it on the list.
Are there any better models for the Airships, they look pretty cheesy.
not for now
or I remove 1 airship to have only the zeppelin model (a hot air balloon would be nice as a 1. airship but so far there is none for Civ5)
