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. Warlords: 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) Caste System no +1 from Workshop, Slavery low upkeep (not medium), Emancipation no upkeep (not low), Environmentalism no +2 from Windmills but gets +1 from Jungle and Forest, State Property no +10% Expansive gives 50% worker bonus (not 25%) (see below for further change in vanilla) Railroads require Coal (Oil not an alternative), no Forest Preserve Simple Forts (can only be built within own culture borders, do not give access to resources, cannot house naval or air units) Factories no +2 from Coal and Oil Cavalry does not require Rifling, Trireme does not require Metal Casting, Grenadier requires Chemistry (not Military Science) Greek Phalanx replaces Spearman (not Axeman) and no free March promotion, Japanese Samurai no free Drill I Barrage available to Armored Units 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 No Espionage Points system, Spy requires Scotland Yard national wonder, demographics always visible No Corporations No Colonies (no specific Overseas Maintenance Cost), no City Liberation No Random Events No Advanced Flight, Aesthetics, Laser, Military science, Stealth, Superconductors, different tech requirements for: Fibre Optics, Robotics, Computers No Airship, Anti-tank Infantry, Attack Submarine, Cuirassier, Guided Missile, Missile Cruiser, Mobile Artillery, Mobile SAM, Paratrooper, Privateer, Ship of the Line, Tactical Nuke No Customs House, Industrial Park, Intelligence Agency, Levee, Public Transportation, Security Bureau No Apostolic Palace, Cristo Redentor, Mausoleum of Maussollos, Moai Statues, National Park, Scwedagon Paya, Statue of Zeus.

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.
