yeah that was always the issue the Col system it was better to spend than save, which makes some of the features of certain mods difficult to get, as you have to have a big pile of gold at the random moment of the event...
Part of the Col problem with this is if you say save 5000 gold, the king shows up and request maybe 3500. If you spent it and have 500, the king asks for 300. This (intentionally or not) is a real killer for stashing money.
You did give me an idea. Random events costing money shouldn't be a here and now offer, but an offer you can reply to all turn. That way if the price is 2000, you can borrow 2000 from another player (like city state) and then accept the random event offer.
Medieval times had an interesting option for interest in such huge loans. It could be the right to collect taxes in a certain area. King A borrowed money from King B and then King B could collect taxes in an area of country A. Sometimes those loans were never repaid or king B refused to accept repayment, which meant it turned into buying land, which moved borders. In other words modern day borders are still affected by unpaid medieval loans.
When a king had the right to taxes for an area and he knew he would only keep it like 5 years, he usually had insane taxes meaning when the owner got it back the population had become poor and no longer paid as much tax as they used to.
Also, right now I made it so you can only play some of the European Civs and removed the Vikings, Arabs, and Mongols from human play.
Last time I checked the Vikings came from Scandinavia, which I'm pretty sure is placed in Europe
I plan to do something different for other Civs. Like the Vikings and Mongols will have a different objective than the others, more about conquest..
The question is if Vikings are even comparable to the other invaders and if they were invaders at all. Sure the monks wrote that they were, but not all historians are so sure. It depends on how you value written evidence vs non-written evidence.
The viking era started like this:
Monks arrived in England and gradually took control in the 6-8th century.
Monasteries started to send missionaries to Scandinavia in the 8th century (maybe before but the first written account is from here).
793 vikings attack Lindisfarne, which worked like a capital for monasteries. They burned it to the ground and left no survivors.
Monkwearmouth-Jarrow Abbey took over the leader role and the vikings burned it to the ground the following year.
I'm starting to see a pattern in those attacks. There is no real evidence of vikings sacking villages. Those tales are written centuries later.
Another interesting twist is the Battle of Brunanburh in 937. England attacked Scotland, but at the time of the battle itself Scotland had help from Ireland, Scandinavia and Iceland and together they managed to drive the English king back. Why would vikings die in battle to help Scotland when they could have been sacking Scotland while the warriors were busy fighting England?
The really interesting twist to the story is: who were the local population?
Tacitus (Roman) wrote about a Scottish tribe that it was Danish because they shared language and customs.
English uses norse grammar with loanwords from non-norse languages. This indicates norse speaking people being forced to adapt to another language, not the other way around.
More than 2000 norse placenames are in Danelaw. Arguing that they were because the vikings went through would be like stating that France ditch their French place names and started using German ones even after WW2.
Norse placenames outside Danelaw.
English weekdays are still named after the norse gods (except saturday, which the Romans named after the god Saturn).
Scottish and English (specially in Crumbria) has a surprisingly high number of norse "loadwords"
All in all the question remain who invaded who? Did the vikings invade foreign England or did the monks invade norse England and the norse people fought back? Historians will most likely never agree on this one.
And how does the role of vikings affect M:C? I'm not quite sure.
