Game Play Differences Between Expansion Packs


Feb 24, 2011
The following is a list of the main differences a BtS player would see when playing a Warlords or vanilla GOTM. The aim was to produce checklist that could be read in a few minutes, covering the most significant and the most often forgotten differences between the games.


  • Anarchy can occur during Golden Age, first Golden Age uses two Great Persons (not one), no +100% GPP
  • Space win occurs at launch, capturing or razing capital does not destroy completed components, all components must be built, different tech requirements for components (see below for further change in vanilla)
  • Siege can kill, no Flank attack against Siege, Siege can attack from boats
  • Key interface differences - no prechop control, no WHEOOHRN indicator, no capitulation alert, cannot examine captured cities
  • Stonehenge and Obelisks/Monuments obsolete at Calendar (not Astronomy)
  • Captured Workers can move on same turn
  • No gold from excess production overflow
  • Simple air combat and no air promotions, no XP from airports, unlimited air units per city (not max 4, 8 with Airport)

  • Great General generation needs less combat experience
  • Workboat does not become ocean-going with Astronomy
  • Workboat, Galley, Trireme and Ironclad can enter an ocean tile within foreign culture borders with Open Borders or when at war with the controlling civilization (cannot do so in BtS, except ocean-going Workboats)
  • No Blockade, no Sea Patrol, no Pillage of naval trade routes
  • Trade by river does not require Sailing, can trade obsolete resources

  • Less civs and leaders <Added in BtS>, Augustus Caesar is Creative and Organized (not Industrious and Imperialistic)

Vanilla (in addition to above):

  • Building research/culture/wealth gets 50% (not 100%) of :hammers:, and bonuses from Library/Bank etc apply, but not from Forge etc (opposite to WL and BtS) (so often better to build research rather than wealth in vanilla)
  • No Great Wall, Temple of Artemis, University of Sankore
  • No Trebuchet, Trireme
  • Chariot does not get +100% against Axeman, Siege can receive collateral damage
  • Civil Service does not require Mathematics (Oracle slingshot affected)
  • Can preselect an item to build in captured cities for free turn of production when they emerge from resistance
  • Production from chops happens immediately on completion, no opportunity to change build target that turn
  • Production from chop is lost when building research/culture/wealth or when no production item is selected
  • River deltas provide fresh water to less tiles
  • Workboat, Galley and Ironclad cannot enter an Ocean tile within enemy culture borders when at war
  • Resource bubbles point toward the equator

  • No Unique Buildings
  • Less civilizations and leaders <Added in WL> and many leaders have different traits <See Old Traits column here>

List originally compiled by psparky, following a suggestion by Deckhand. Far too many people to credit them all here, but if I used your input, then thanks!

Moderator Action: Thanks go to psparky who compiled this list to help players to deal with game-play changes as they move between the three xOTM series. The original discussions can be found in this thread.
Do chops get you more :hammers: in vanilla or am I imagining that?

I think it's the same - 20 (within BFC), 30 with maths.

The Warlords Manual indicates a reduction compared with vanilla (I think it was originally 30 in vanilla), but the same reduction was made in the 1.61 vanilla patch.
Hammers from chops depend only on speed. 13 on Quick, 20 on Normal....... before modifiers of course.
I also received a +40 chop in the capital on this GOTM making me check the speed. There is something to investigate here...

Please be very careful not to reveal ANYTHING about a current GOTM. In this case I guess you were building an early barracks, for which you get double hammers from being aggressive. But there are other combinations that can give this result.
Maths + forge + a building you can get for cheap thanks to your trait = over 60 hammers I think :)

Are there fewer promotions available in vanilla too, eg Woodsman 3? I'm at work at the moment so can't check.
After stumbling on this old post, I verified and now confirm there is a small change from Warlords to BTS for horses archers. Indeed, a small handicap of 10% against city attacking was implemented in Warlords expansion, but it doesn't exist anymore.

Really funny that this non-bonus is shown green as it was a bonus in odds showing.

So, in Warlords, there was a difference of 20% between swords and HA's. Interesting when making choice of classical rushing.

Also, there is no intercontinal trade route bonuses in Vanilla(and Warlords). In BtS there is an +100% bonus, which makes routes +2 (with own cities) and +3 (foreign cities) from start. This makes a big difference/advantage on archipelago maps on BtS
Here are a few more differences between Warlords and BtS:

1. In Warlords (and Vanilla), you can win a Diplo victory by owning 62% of the total pops and voting for yourself without the need to have an AI vote for you (i.e. Diplomation). In BtS, if you have more than 62% of the total pops, the UN Diplo Victory option won't even be available as a possible vote.

2. In Warlords (and Vanilla), begging/demanding gold does NOT enforce a 10-turn peace treaty. This means that you can demand all of an AI's gold on the turn you plan to declare war on them so that they have no gold to upgrade their units.

3. In Warlords (didn't test Vanilla), TRs are set up between your own cities on the turn after they are settled even if there is a connection between the two cities (i.e. roads, rivers, coastal + sailing) when the city is founded. In BtS, if there is a connection, you'll get the TRs between the two cities on the turn you settle.

4. In Warlords (didn't test Vanilla), the AI do not automatically meet each other when the UN is built. So there is the possiblity of an AI not even knowing one of the UN candidates.
Many thanks to All. :thumbsup:

Thank goodness most (all?) GoM's stick with normal speed, otherwise the variations would be exponentially greater/more confusing(!). :confused:

I can confirm for vanilla. I had a two continent game where Greece was landlocked and surrounded by Japan and Russia (and impassable arctic). These two were not giving out open borders very easily, and Greece did not have any access to the ocean, so many of the civs on the opposite continent never met them.

I was one of those civs on the other continent, and it took quite an effort to meet Greece. I don't think I made contact until 1908 AD or so, well after the UN was built.
