Its becomming laughable now that ppl are saying there is not enough stuff in civ 5 with compare to the other civs.
Here is a rundown of your issues.
Vanilla Civ IV
Civilization IV comes to life - Beautiful 3D world with dozens of fully animated units (including culturally unique units), and totally customisable armies. Cities and wonders will appear on the map. Wonder movies are back!
Faster-paced fun - Gameplay has been streamlined for a tighter, faster and more compelling experience with an easier to use real-time strategy style interface.
Multiplayer - LAN, Internet, PBEM and Persistent Turn-Based Server (PTBS) offer players all-new strategies and ways to play when competing or cooperating with live opponents.
Team Play - Whether playing multiplayer or single player, team play offers a new way of setting locked alliances that result in shared wonder effects, visibility, unit trading and shared territory that delivers a plethora of new strategic and tactical options.
Mods and Community Tools - Designed from the ground up for modability, the game contains a powerful map editor with XML and Python support.
In-Game Movies - Civilization IV will have over 70 in-game movies.
Warlords
Warlords: A new great person type called the Warlord.
Vassal States: Conquer an enemy and subjugate them to your rule.
Game Scenarios: The expansion will deliver six scenarios.
New Civilisations: The pack will provide 6 new civilisations and associated unique units.
Civilisation Leaders: Ten new leaders will be provided - the list will include leaders for the new civilisations as well as additional leaders for existing civilisations.
Leader Traits: Two new leader traits.
New Wonders: There will be three new wonders.
Unique Buildings: Each civilisation will have a new unique building as well as their unique unit.
New Units, Resources, and Improvements: Many new items will be presented throughout the scenarios.
Core Game Tweaks and Additions: Expanded features and gameplay tweaks will be made to the core game.
Post-Release Patches and Game Upgrades: The pack will contain all of the patches and game additions (pit boss, etc.) yet released for Sid Meier's Civilization IV.
BTS
More Civilization Than Ever: Some call Civilization the deepest computer game of all time. With a massive increase of 10 civilisations, 64 buildings, 12 scenarios, 5 wonders, 6 technologies, corporations, brand new espionage system and expanded trade routes, Civilization is beyond deep. It is beyond anything you've ever seen.
Focus on the "Late-Game": With Firaxis focused on delivering many new units, buildings and technologies in the modern time period, you will be able to launch guided missiles and suitcase nukes and build armies of mech assault soldiers, Cyborgs and Navy Seals - among many other choices.
Scenarios - Expect The Unexpected: Beyond The Sword will deliver 12 new scenarios, many containing themes never seen in Civilization, custom designed by the team at Firaxis and some members of the Civilization fan community.
Advanced Starts: For the first time ever, launch a game by purchasing units, cities, improvements, and technologies that allow you to get into later era games more quickly.
Unstoppable Corporations: If you didn't feel like behemoth corporations were taking over the world, you will now. Found your own corporation and spread its influence as another tool to gain control over the world.
BTW this is fact. Alot of the CIVS/Building/Resources/Espionage/Corporations were added with the expansions. All I can say is, if you are not happy with the vanilla CIV V. DO NOT play it. Stop moaning and move on to another game.
