My players will only be sold on playing D&D if I re-skin the setting into something sorta historical. Rather, they're bored of generic fantasy settings set in pseudo medieval Europe.

No problem! That's actually not very challenging for me.

So far, the time period and place that interests everyone the most (including myself) is fantasy Ancient Greece.

I'm okay with doing my own research, but I wanted to see if anyone here has done something similar or has any recommended resources.

I have plenty of books on greek mythology and history, but I'm looking for gaming-related resources... and I'm sure that not all game books are equal in quality .

TL;DR: Would anyone like to share any advice or suggest some gaming books that would help me GM D&D in Ancient Greece?

I don't know the quality of any of these first hand, but

  HR6 Age of Heroes is the obvious first stop, and reviews are positive. Nicky Rea didn't do very well at co-managing the 3E Ravenloft line, but her Guide to Transylvania for the 2E Masque of the Red Death subsetting was pretty good.

  HWR2 The Milenian Empire is apparently a Gazetteer for the quasi-Greek portion of the Hollow World.

  Mythic Greece: The Age of Heroes is a Rolemaster/Fantasy HERO product (reportedly more FH than RM), and again, I can't speak to the quality, but while it's pricey, it's also an Aaron Allston production.

There was a 2e sourcebook for just that sort of thing if I recall correctly. I think there was a book for d20 that was ancients or something along those lines.

Maybe look for something in GURPS?

GURPS is sort of my go-to for sourcebooks... yeah, not d20, but...

Mazes and Minotaurs and all the fluff from the Minotaur Quarterly immediately come to mind.

How good is your German? the Chryseia setting for Midgard is a not overtly detailed but just quite nice fantastic-hellenistic setting with quite some potential . And if you have some money to waste, a few truly excellent adventure modules (Die Schwarze Galeere is okay, Ein Hauch von Heiligkeit and the follow-up campaign is just incredible).
Otherwise, there is a Gurps book (of course there is). And it is comprehensive and quite good (of course it is) and a bit dry to read, and more of a tool box than a concrete setting (naturally).

Your prayers to Olympus have been answered!

MAZES & MINOTAURS

It's free.
It's got lots of free supplements.
It plays absolutely awesome!

Doesn't Pundit have Lords of Olympus?

Holy crap! Thanks guys and/or gals. This is a great start.

I was playing a fantasy Greece campaign recently, and it is one of my favourite periods in general. For the books I sadly mostly know the Polish researches, so I'll be hard pressed to give advice. If you can find translations of works by Świderkówna, I highly recommend reading them - they are about Hellenic not as much Classical period, but we know much more about that period either way, and I doubt many players'll take notice if you give in mindsets from those periods every now and then.

My advice'd be:

1) Are you going to have Ancient Greece with fantasy elements, or Fantasy Ancient Greece? There's a good amount of difference here, as one game'll require a tad more research and grounded approach, but also gives players even greater ease of knowing the world and for you a ready timeline of events, but on the other hand - a risk of history buffs going wild over the inconsistencies or "inconsistencies". The other approach lets you go more wild, but you risk the history buffs ranting about why we're not just playing normal Greece.

2) Go wild with city states. We only really know political systems of two states in great detail - Athens and Sparta, and look how different they were.  Remember the Sybaris, the great decadent and rich city, Corinth, the city of sly merchants, Thebes, independent and regal, Megalopolis, famously big, Ephes and Milet, the birthplaces of mathematics and proto - philosophy. Also remember that Ancient Greece's Classical period richest cities were actually colonies in Magna Graecia and Asia - don't make a mistake of locking yourself in the Greece = Achaia and Peloponnese.

If you are playing Fantasy Ancient Greece, do so especially. States ruled by (mad) demigods, states ruled by actual gods, states with absurd laws, secluded city - states where everyone's a "maniac", cities where laws seem innocent enough but turn deadly on visitors, cities ran by rulers who put Paranoia's computer to shame, cities where everything seems great until you actually try living there...go nuts with your imagination. The best thing about city states is that you can have much experimentation with various political ideas, on a relatively small terrain - lots of states, not  a lot of cities to be filled in those states.

3) Remember about outside influences. There were various incursions of "barbarians" from the north and east and west into the Greece, not to mention interactions with Persians, Frigians, Iberian Celts, Italians and Etrusks, Carthaginians and Phoenicians, Thracians, and also various mountain tribes that were half - uncivilised - really, too many to count, to name Aetols as the most succesful of the whole bunch. In fantasy Ancient Greece...oh boy. I myself went with Persians as hobgoblins, Darius riding a dragon into battle.

4) Dedicate a time period, and important event that the game'll most likely be centred about it. The suggestion'd of course be, by me, times of great upheaval, but not necessarily.

* Fall of Achaeans proper and Mycenese culture, so "classic" Mythic Greece - war for Troy, Dor invasion. Might want to look at, interstingly enough, Pendragon to see the general idea, or draw from Arthurian legend there - just replace Saxons with Dors and Anglo - Romans with Achaeans.

* Colonisation period - various interactions with "barbaric" (some actually much more civilised) civilisations of Etrusks, Iberian Celts, Frigians/Hittites (depends on a period), Phoenicians, Egyptians, Crimean folks.

* First Persian War - my personal favourite. Mighty empire on the horizon, it starts out "safe" with the rebellion of the Asian City States, ending gods know where.

* Second Persian War - another safe bet, especially if you switch off your inner historian and take 300's Monsters of Persian Army up to eleven. Or surprise your players with Xerxes less of a god - complex maniac, and more as how Persians saw him at the time - a liberator from another civil war between the priesthood (the Magi - could actually make them literal mages here, necromancers perhaps), who went overconfident with power, a kind of darker Henry the VIII with less wife cutting.

* Peloponnese War - A great war between two mightiest political powers of Greece proper, with everyone throwing their lot with them in an everchanging balance of politics. You think GoT was full of backstabbing? Try that with 40 - 50 city states rather than 6 - 8 biggest aristocratic families. And of course, the threat of Persians in the back, ever present and willing to meddle in policies of their neighbours.

* Macedonian Supremacy and Greece's Last Stand - the campaign of Philip the Second and his son to break the City States, especially worthwhile for Spartan and Athenian attempts at trying to keep the old traditions alive. A kind of "fin de sicle" feel for the Greeks.

*Hellenic Age, Wars of Successor - the last (but perhaps not least) of my three favourite periods. The great dominance of Greek Culture, yet the Greece proper is reduced to mostly dreaming of it's former glory, with some raisings about every now and then, though the dream of "Freedom of Hellens" will only ultimately cause Roman subjugation of Greece. A very worthwhile note - Spartan revival. But of course, the main course is quite simple - ambitious generals, trying to unite Alexander's empire or carve out the largest piece of it for their dynasty.

I endorse Mythic Greece: Age of Heroes. I used it for a campaign I ran using Runequest 2 for the system and converted the Fantasy HERO stats to Runequest. I thought the supplement was good and had some good Heroic* Bronze Age culture and ideas. I'm not familiar enough with D&D 5E to say how well it would work for that.

* Heroic in the sense of the sorts of things that characters do in the Illiad, the Odyssey, the Argonautica and other tales of Bronze Age Greek heroes and in a setting where the gods and mythical beings are real.

Play Tyranny of Dragons or whatever in 5e until Mythic Greece for RQ6 comes out next year.  

Or yeah, Mazes and Minotaurs.

This is one of those things I have to do before I die. I just have to find the right system/supplement and time.

My suggestion is you read Gene Wolfe's Soldier/Latro series. You could probably get the bulk of your setting information just by taking notes. They're ridiculously well-researched.

This. Just be aware of all the (intentional) mistranslations and misunderstandings Wolfe introduces. E.g. Spartiatai doesn't actually mean "rope-makers."

That's just the fun of reading Wolfe.
