The most accurate historical game possible?

Red Orchestra, Arma and COD 1-2-WAW.

Brothers in Arms

It's 100% accurate. The actual story is true, Baker existed

No. Like in Hollywood, drama takes precedence over facts when required. That said, I would recommend Assassin's Creed 2. After I finished playing it, I found myself pleasantly surprised by how close to history it stuck.

Europa Universalis 3 not 100% accurate but more accurate than any other game out there. It has a few false informations like placing Romania and Hungary into the slavic language family although Hungarian is Uralic language , and Romanian is latin , but those are just small details .

Any Star Wars Game, they take place long ago in a galaxy far far away so they are completely accurate for that area...

Stalin vs. Martians.

Age of empires, specaially the 3º one...

Mass Effect

fortix

Secret of the Magic Crystals.

You can not know history 100% accurate. It is changed alot in favor of different politicians. Of recent examples I know, In Ukrain they learn Russian-Ukrainian war at school, while that war never took place in real world.
And what's the point of the 100% history accurate game? That's a game, where you could not influence anything=)

red alert series >.>
nah dunno maybe cod 1-2 and waw
on assassins creed if you read the "history pages" they are pretty acurate.

Napoleon Total War

Skyrim.

Europa Universalis III.

BF 1942, not the story, but the weapons, maps, clothes.
Oh! and SPAZ

Assassin's Creed? ^^

Call of Duty.

Metal Gear

Call of Duty Black Ops and Knights of the Old Republic

Sid Meier's Civilization V.

Well, any game MAY contain false information...

I think there might be some games from 90s mostly turn-based strategy can't name any, but that's the area where they exist.

Monster Girl quest
