Well, in the BG, you would get good money from exotic goods anyway.
Especially with well developped trading post and colonies.
Some countries could get very rich.
However, it did not impact the game in the same way. In particular, Tech increases were not affected as much in the BG by revenue as in the CG. If you had lots of money, what would happen is that :
- you'd spend a decent amount on upgrades (traders, colonies, tech...),
- probably maintain a sizeable army and fleet,
- keep some in your coffers to rot under inflation (much worse and realistic in the BG than in the CG).
Some of the very important differences are :
- in the BG, you may make one attempt each turn (every 5 years) to increase your military tech (choose one of navy or army),
- in the BG, you may make one attempt each turn to increase your infrastructure or trading techs or install a new manufactory (choose one only)
each attempt is influenced by :
- monarch rating (1 to 9, usually between 4-6)
- money poured in the attempt ; but the bonus would not exceed +3 (if I recall correctly)
- possessed manufactories for military techs only : +1 for each manufactory of the right type, max +2
And then, you would roll a d10, and you'd have to get more than 15, if I recall correctly still
Obviously, monarchs values where alwasy very important, and if you had a monarch who sucked, your tech would not improve much, even if you had lots of money (he just is not able to apply all his money to the right things). On the other hand, you also see that if you had a monarch who rocked, you could make quite good progress, even with little money (you still need a basic amount of money to progress) Does Frederick I reminds you of something?
As you see, it is not as much the amount of money you make which makes a huge difference : it is the way it is used. And in the CG, a monarch is very useful at the start of the game, and you just don't care if your monarchs suck at the end : you make so much money that the monarch input is negligible ; in the BG, just try and play historical monarchs for Spain or Turkey up to the end of the game, and then you'll understand what is a badly led country
Now, if I were tweeking the parameters of the game, I would attempt a combination of these :
- reduce the number of colonists you get overall by 5 (would that be possible ?) ; consequences : much less high profits colonies/trading posts ; nobody can monopolize a given area ; and, of course, trading revenues go down hard ; also, because you really need a return on your first invetsments, traders become much more necessary (I never use traders, except to 'reserve' areas to colonize later)
- reduce the costs to increase tech : make each step linear (slightly increasing cost) instead of exponential ; keep it low. exact values to determine of course, but also probably to stabilize (to keep it in line with your earnings)
- reduce the overall effects of infrasture and trade technology (diminish the increase in generated trade) ; in the BG, these techs only gave you a better chance of success at some action ; you did not make more money with them. I'd say that the increase should not be more than 2% or 3% (but of course, you need it much less because tech is much cheaper). I would even try and see if a "no increase" in revenue would be playable (i.e. do your techs affect success chances or not ; I'd say yes : my lvl 10 merchants seem quite resilient, and success when placing a merchant is quite good too).
- probably reduce the overall trading values of all commodities (I believe a factor 2 or so).
- the size factor for countries should also be tweaked if possible (to reduce the bonus small countries would get under that new model).
- something probably not feasible : don't divert Chinese trade so easily to Euopean CoTs.
That's about all ; overall expected effects : much less money overall (especially in the second half of the game).
- Monarchs much more important.
- Much less colonies : placement becomes crucial.
- With less money, troops are costly, maintaining large armies is costly, thus making war is not a necessarily winning proposition.
- Diplomacy (with cash) becomes less frequent : much more difficult to make vassals and such.
- All in all, with less money, you just cannot afford to do everything you wish ; in the BG, you sometimes skipped whole phases (no increase in techs...) because there was no money left...
If someone tries something like this, I'd really be interested
