Things you learned from playing vanilla RTW

[Connacht]

I learnt that any general in the ancient world was a ultra-dumb asshole unable to perform just a little skilled tactical movement (that's the reason for I think that RTW is a lot overrated, too stupid AI).
I learnt that the Carthaginians spoke like stereotypal Arabs.
I learnt that eastern factions like Parthians or Pontus were sons of the desert and praised it like stereotypal beduins - although they still could gather thousands and thousands of footmen in the sands.
I learnt that beduins were very common mercenaries.
I learnt that in today's Poland there was a German settlement named "home sweet home" in Latin. XD
I learnt that any hoplite was in a Macedonian phalanx.
I learnt that even if wearing not so martial clothes, the Spartans were so cool, but so cool, that they could face the mighty of any huge enemy army and still exit victorious from the battle with few casualties, high morale and without fatigue.
I learnt that Cretan archers garrisoning the island before the Roman conquest were skilled as samurai in handling their swords.
I learnt that the Mediterranean sea was full of invincible pirates that forced the naval powers of the time (Carthage, Rome, Greeks) to take a lot of kicks in their asses from them, even with many triremes against a little boat.
I learnt that the Iberians were skilled shipcraftsmen.
I learnt that the Romans were so advanced, but so advanced, that the other people felt the need to copy their soldiers even before they actually become available to the Romans themselves.
I learnt that in every battle is necessary to say that the Roman gods are watching and blah blah blah.
I learnt that Germania was a Nubian colony and Nubia a German colony.
I learnt that ancient kingdoms, even if incredibly small and surrounded by overwhelming ultra-powerful empires, were costantly in full suicidal war, until everybody but one will die ("There can be only one").

Now let's talk about Barbarian Invasions:

I learnt that the Franks had their Paladins even in the V century. Now I want a Charlemagne unit!
I learnt that the Orthodox church existed centuries before the schism.
I learnt that Spain was already fool *ehm* full of Moors.
I learnt that the Huns invaded central Europe and Italy before the V century.
I learnt that the Sarmatians that with the figure of Artorius Cassus inspired the legend of king Arthur and above all the movie King Arthur were really the bulk of Roman and especially Romano-British armies!
I learnt that the Germans called themselves with Latin or English names depending on how they woke up that morning.
I learnt that Berbers were already Muslims.
I learnt that Slavs invaded Europe just a little after the Huns and the Germans.
I learnt that German settlements were called in honour of Roman tribunes, or perhaps resembling today's English word "tribe" in a sort of Latinorum.
I learnt that Goths and Vandal were Mongolic nomads.
