Fallen Enchantress is full of snowball effects like this. I like it for that, it doesn't restrain you and lets you do ridiculus things (ever try the refined research singularity?)

I have never got that far into a game without either getting bored because it is trivial now, or winning.

What turn are you actually on?

Not sure this example is applicable to the game in general.  It's an abnormal situation you've created here.

I have the same question.

But yeah, money really isn't that useful in this game beyond rushing items.

Unless you have Betrayers, then you can literally buy the world!

isn't there some famous quote that "compound interest is mankinds greatest invention"? (I believe Adam Smith or Albert Einstein - really not sure)

i find it pretty funny actually that you can create such an insane situation, but i think most games are over a lot earlier so this kind of silly scaling doesn't affect the majority of games. i don't think I ever played a game of FE that took more then maybe 250 turns.

though with the new production scaling at game setup, i can see myself playing huge/epic tech/medium [default] production setups for the sheer epicness (i didn't like the old epic setting because it also slowed production down). very long games may become more common with the new huge maps, so it's probably a good idea to limit the maximum amount of extra gold (as Foxcat suggested)

As others have said it is only compounding so massively because you have already won but choose not to take the victory.

Think about it, you have 2.3 million guilder in the bank. You could have used a fraction of this money to buy troops and steamroller your opponents ages ago. It is only because you haven't that you have so much money.

In a competitive game where the player is struggling on an even footing against the world and the AI they would be spending that money before it could accumulate to any significant level.

In summary, it isn't your 60k income that is unusual, it is the fact that you were winning by so much that you could afford to save 2.3 million that is unusual.

I suppose you could rush buy Spell of Making towers and win the game.

But overall it's not very OP. Typically if you're dependent on gildar to begin with, you probably spend a lot of it; So your initial gildar bank is pretty low when you start getting 1%g/turn. At least that's what I have found in all my big money Capitar adventures.  Maybe what needs to be fixed is that the bonus is multiplied by town/structure bonuses. Other overall bonuses like Research/Faction/Race should increase the amount you gain.

Quantity over Quality for units doesn't always work anyway. In a standard game you wont be able to rush buy full Champion Armour knights and flatten everything from one side of the map to the other (exaggerated example).

OP is a big Warcraft fan

Map is called "The Wildlands". The city has catchy unique graphics:

Not really for years, but reaping for large estabilished lore help when you have to name 33 cities

Not really. A game planned to be long was done with all the sliders to the slowest setting (research and production). Now the Refined Economics takes 3 turns researching with 1560 research per turn. But it was still way longer (8-9 turns if I recall good) when I took the first screenshot.

I finished the game at turn 809, with 31 millions in bank and 1 million gildar per turn. If I remove the treasury vault, my gildar per turn becomes 1769. But I could never get it so high without all those money, since (after starting this thread) I tried to found many cities and rush them all to level 3-4 (spamming consulates). The +10% gildar still feels much more balanced.

Still you're right about game not being balanced around long games, and I see my error now after the good input in this thread.

Oppressive taxes?

I think some of you are missing the point and only looking at the super high numbers. Treasury vaults are overpowered the moment you build them. The snowballing starts with much lower numbers, tens and then hundreds, but that's still enough to cover all your expenses and suddenly watch your gold grow more and more rapidly every turn. It might take a long time to get into the millions, but that's not the point, because the moment you build one you can pretty much start ignoring your economy.
