Yeah man, the most known AOE bonus to me is probably Hittites with their +4 range ships, but don't get Triremes. Assyria's faster firing archers, Greece's speedy phalanxes, Persian elephants, Egypt priests +3 range or their chariots with extra HP, Shang's cheaper villagers, Choson's +80 HP Legions and extra tower range, Sumerians 50% faster firing catapults, Minoan +2 range compies, Yamatos cheap cavalry and horse archers, and Babylonians walls and towers had extra strength. Phoenicians faster woodcutters.That's pretty much it.
One of Age of Empires strengths over Age of Kings, or more specifically, The expansions for Age of Kings is how simole and focused the strengths of each civ are. Greeks get their architecture, tech tree and 30% faster warships and hoplites. That's it. Yet they are a fun late game civ even if every time you see them in random map you can't help but think how doomed they are.
Contrast with later civ, say the Celts. Ok, 15% faster infantry, that's pretty simple if a bit underwhelming - hoplites are the TK of AOE. But the Unique unit Woad Raider requires an expensive castle Nd is not useful until Elite in Imp, when it is upgraded. And you've got this small woodcutting bonus and a decent siege bonus, although it's not very strong on its own. But if you get the Unique tech furor Celtica, you will have much more HP..
everything is spread out and feels watered down. It takes too much investment before you can use these bonuses because they're not good until they synergize at some point. Sort of like an RPG where you get skills but need to invest wisely before they realize their potential.
Contrast to something like 30% faster elephants, +4 range, +80 HP or 30% cheaper villagers which is more like a badass weapon/gear
Well basically the Tldr version is AOE bonuses generally make their special qualities and utility immediately apparent and obvious but AOC civs require significant prep time / investment / planning beforehand because of the way the synergies are spread out all over the place and they aren't so easy to see, usually. Unless you're Huns. (Seriously, no houses and cheaper horse archers would fit in just fine with the other AOE civs). I say AOC and not AOK because AOK has no Unique techs.
