Warcraft III: Reign of Chaos / Reforged: Fantasy RTS, heroes, distinct races, magic—very AoM-like.
Turn-Based Strategy with Mythology
Heroes of Might and Magic III (HD/Complete): Empire building, hero development, tactical combat, deep magic/monsters. Not real-time, but scratches the mythic strategy itch.
Other Genres
SMITE: MOBA; play as gods from many pantheons. Direct mythological combat.
God of War Series: Hack-and-slash action; Greek/Norse mythology, epic narrative.
Assassin's Creed Odyssey: Open-world RPG; deep dive into Ancient Greece, gods, myths.
While not clones, these offer the mythic strategy or action fix AoM fans crave.
