The static const are set in src/currency.cpp . Approx. half of entries are off. I could make a new version, but I'm unsure about the approach.

Should i take the historical average from past 10 years? past 5 years? Should i take the exchange rates for now-euro-currencies from the year of euro-arrival for that one?

The conversion rate only affects the display of currency amounts. It does not affect the game mechanics. As such currency factors change original pound prices into different numbers.

Thus I have a counter proposal: All fractional exchange rates are removed, only pleasing factors like 1, 2, 5, 10, 20, 50, ... are allowed.

This has these advantages:
- Round numbers remain round numbers: E.g. the loan interval of 10k£ is converted into 20k, 50k, 100k, ... or similar, but not into 13734.
- The conversion rates are still capable of representing vast differences in worth, like 1€ = 2000 lira (but not 1936.27 lira).

Using exact conversion rates has no advantages:
- Conversion rates change over rate, so any exact rate is completely arbitrary.
- Prices in OpenTTD have no relation to real world prices. Even when not using inflation in OpenTTD, I am not aware of anyone having tried to balance the game using historically correct purchase prices.

The DB Set uses historically correct purchase prices.

Having to review the actual currency rates is not something that is going to work in the long run. Furthermore, having currency rates change during the game can cause some nasty surprises too.

In any case, definitely not a bug that can be fixed correctly... unless you're suggesting that we are going to model the different currencies throughout history...

andythenorth closed the ticket.

Reason for closing: Won't implement

Not a current gameplay goal for OpenTTD. The goal of equivalence can be met by everybody using the same currency. Flyspray clean up, closing. Thanks :)
