Great FirewallWorld Wonder: Great Firewall

Tech Required: Computers

Production Cost: 1250

What it Does: Requires Gods and Kings. Reduces Enemy Spy Stealing Rate by 99.9% in the constructing City while providing a 25% reduction in all others. Gives no Culture or GPP. Negates the double Tourism benefit of other players' Internet Technology.

Strategies
Build this Wonder in your highest Science-producing city to dramatically reduce enemy spies' theft of your technology. I'd only consider it with a tech lead, otherwise it'll be useless. You can follow up with other anti-spy buildings in your other Cities to make your Civ's security very tight, especially if you plant a Spy in the same City as the Firewall to kill off enemy Spies, although this does free you to use your spies for offense or diplomacy if you are not the only Civ with a technological advantage and have someone you can steal from yourself.

It does come so late that if you need this, you are likely already well on your way toward a Science Victory. Few would call this their favorite wonder, and even fewer label it essential, but it does have its uses in certain situations... particularly if an enemy is close in Tech and competing for the same type of win.

If a Civ is heading toward a Cultural Win, you can use this to stop them gaining influence on your Civ so fast by knocking out their Internet +100% bonus. This can help a lot and even let you stop them entirely if your cultural output is high enough. This can be built defensively to stop spies, stop a Culture Win from another Civ, or both.
