Shadow of the Colossus is allegory for the Jews conquering Europe.

The main character Wander is the Wandering Jew. The woman he seeks to revive is called Mono (Monotheism of Judaism).
A spirit called Dormin residing inside a massive central tower promises to revive Mono if Wander defeats the Colossi. Dormin backwards is Nimrod, the biblical character behind the tower of Babel. Note: EU parliament building resembles the classic painting of tower of Babel.
Each Colossus represents a European nation. Wander must locate and attack the Colossus' weak points like a subversive Jew. As the Jewish diaspora is small, the metaphor of a single man taking down a towering colossus is fitting.
The game was published in 2005 & contains 16 Colossi. When the game was in development, the EU contained 16 nations states.
Europe consists of 50 sovereign states and territories, and originally the game was supposed to contain 48 Colossi, so pretty close to that. That number was reduced to 24 (in 2004 the EU had 25 nations) but these were scrapped. Was the addition of 8 states to the EU in 2004 too much work for the staff to add so late in production?
Like nations the Colossi are varied, some are big and slow and dull, others are small and fast. Some destroy themselves and their surroundings trying to fight off the Jew.
As Wander conquers them, he gains their power, eventually taking on the form of Dormin itself. The biggest and baddest Colossus of them all is also incomplete and thus shackled at the waist. This represents the Third Reich, incomplete when destroyed, but would have been terrifyingly powerful had the Nazis succeeded in WW2.
Agro the horse is meant to represent the shabbos goyim. Agro = Anglo. If you've played the game, you know Agro is seriously injured helping Wander, like the British Empire after WW2.
Some theories have already touched on the Dormin / Nimrod thing but none have caught onto the Jewish takeover of European nations subtext.
