At last, GOD heard my prayer
Someone is making a Campaign Featurin the Incas
But, to correct you:
Sacsayhuaman was in the surroundings of Cusco. Machu Picchu was the hidden citadel, I was just "recently" discovered in 1911.
In the Manco Inca's Revolt, he sieged Cusco and his base was in Sacsayhuaman, a known place in that ages.
I'm proud of beeing a Peruvian, even if the actual government sucks.
