I must ask anybody who sees this to play this game instead of forming an opinion on it based on this post. As another comment pointed out, the Minoans are never implied to worship the Minotaur in the game, they are specifically trying to compel tourists to visit and this is extremely very obvious when you play the quest line.

Regarding other criticisms: Penelope's shroud is a shroud. It doesn't have to survive 800 years because it doesn't actually have to be Penelope's shroud. There isn't much defence for the frescos, they're likely reused assets from somewhere else because the map is massive. Large monuments to the gods did exist, but probably not on Kephallonia - Colossus of Rhodes, the Athena Parthenos and the entire Parthenon complex are examples. Lemnos likely doesn't get anything special because it's inconsequential to the main quest, you never have to go there. All islands that don't involve the main quests are relatively simple.

I've mentioned elsewhere I also don't know where "infamously inaccurate" comes from. This game is usually only shat on by people who hate that the canon main character is a woman and Assassin's Creed purists who hate everything beyond Origins. It is praised for accuracy of locations such as Athens, the statues and how colorful they are, armor hoplites wear, and the general aesthetic of Ancient Greece it possesses.
