Well, FWIW, I am not playing Spain anymore with the nerf - I just load up an older version if I want to do that!!
I liked the extra Scout, but only because I was on a mission to find every Natural Wonder as early as possible for the Gold. Without that, the Scout doesn't do a whole lot other than maybe popping an extra ruin or two before the AI gets there (or maybe finding a CS first for a whopping extra 15 gold).
Without a UB and underwhelming UU's for anything Tall/Peaceful, she has a really hard time keeping up without that gold boost, IMO. I think maybe reducing the amount to 100 gold would be a good compromise. If you try to do it with extra gold per city then she loses the tall option if she wants to take advantage of that UA.
I don't know, Isabella just seemed so versatile to me and opened up all options depending on starting position, proximity of AI, etc. With that gold, she can choose to emphasize expansion, production, Wonders, conquest, or any other victory condition. I just found it to be fun not having any idea how I would try to win with her - just adapting to the situation added fun/strategy.
Otherwise, it's not a huge deal. There are plenty of other Civs to choose from!
Going to try Bismark for a Conquest win like Thal suggested and then it's on to Egypt for World Wonder hoarding!!
By the way, if you want to fix the gold problem, I don't think Isabella is the primary culprit. AI's buying luxuries or strategic resources with little need for them at full price is the biggest problem - especially so early in the game when gold is exponentially more valuable (like everything else EXCEPT for happiness). It stunts their growth, reduces their ability to enter into RA's, and just generally sets them back in all areas (except for a faster Golden Age - which means close to nothing that early in the game). Having said that, I fully realize that without our abilityto raise gold like this, humans would be in a real bind more often than not. I just wish there was a way to fix it where the AI didn't have to take such a huge hit to allow humans to stay competitive.
I fully expect that the unavailable game code would have to be changed to fix that. If we could, there should be a general market where various luxuries/resources are put up for sale. Like real life, if you can corner the market on a resource, you could demand a higher price (supply/demand).
And why they got rid of science trading is a mystery to me. I assume that humans were just so much better at it that the AI's would be left in the dust.
Oh well . . . on to Bismark and Rameses!!
