Nice! I will try my best to participate in this. Thanks for making a long deadline!
Here is a list of notable changes posted by
@Dhoomstriker from another thread:
- In Vanilla, capturing an AI's capital (or an AI capturing your capital) can destroy Space Ship progress, if I understand the list correctly
(<--- I think this applies in BTS as well)
- In Vanilla, the Space Elevator is often worth building due to differences in the end-game tech tree, such as Robotics being needed for a Space Ship Part and the Space Elevator only needing Robotics to start building it
- In Vanilla, Research and Wealth build items start off at 50% Hammers and are not augmented by Hammer-multiplying Buildings such as Forges, but are augmented by Libraries, Universities, Observatories, Research Labs, Academies, Oxford University, Markets, Grocers, Banks, and Wallstreet. Since Space games often last long enough to build a lot of Research and Wealth, the tech path and build items chosen can be quite significantly different
- In Vanilla, Calendar obsoletes Monuments and there is no Mausoleum of Maussollos Wonder, so it is a tech that often comes with a bit of pain to research, making it less of a no-brainer to take the tech in trade for access to extra Happiness Resources
- In Vanilla and Warlords, Factories have no Health penalties from Resources such as Coal and Oil
- In Vanilla and Warlords, there are less techs, so there are subtle differences. As one example, without the existence of the Aesthetics tech, you must compete harder with the AIs to build The Parthenon, as that Wonder gets unlocked really early on at Polytheism. Also, since Alphabet leads directly to Literature or Drama, you can either beeline The Great Library or beeline an unlocked Happiness Slider while still being able to trade techs with AIs who haven't teched Alphabet themselves. Meanwhile, Alphabet does not lead to Currency, so you have a different set of choices when evaluating whether to go for Mathematics (which unlocks Currency) or Alphabet after Writing
- In Vanilla and Warlords, Spies work significantly differently, such as requiring Gold, not Espionage Points, for Missions, and only being buildable out of a City with the Scotland Yard National Wonder, which is built like any other National Wonder (in only one City) instead of being a specially-constructed Building made from a Great Spy (Great Spies also don't exist) and instead of Spies being buildable as a Unit out of any City
- In Vanilla and Warlords, Religions, not Espionage, can control visibility of AI Cities, which can encourage you to more actively spread a Religion to AI Cities
- Some Leaders have different Traits, such as Saladin not having the sucky Protective Trait in Vanilla and instead having Gandhi's BtS Traits but with a decent Unique Unit that can engage in combat
I'm sure there is a more complete list somewhere.
We have to choose between two different versions, 1.74.004 or 2.13.004, which both probably are quite unfamiliar to the BTS player. Could someone share some light on some key differences between these and how they play out in space games? Somehow I've got the impression the AI is more aggressive in Warlords. Is this correct?
Are there any notable differences in the interface of the different BUFFY versions? Do workers automatically stop after pre-chopping? Does map finder work with both Vanilla and Warlords?
Edit: Just noticed the much more extensive list posted by NZ earlier. Also provides info on interface changes.
