Link account ESO AoE3 to AoE3 DE

Hello, i’m a french player and i’m looking for help please.

I’m an old player of AoE 3 and i just bought this Definitive Edition. Its a new account, and i need help to link my ESO account to Aoe3 DE please.

Hello, AoE3:DE is played over new dedicated servers and does not use ESO, nor offers any kind of linking between ESO. On DE you log into multiplayer seamlessly without having to input any kind of credentials; the game simply uses your Steam account information. Also, DE has entirely removed the card unlocking grind from the game, meaning that you can use all cards anyway on any account.
