one thing that really irritated me about the AI was it surrendering without asking during the beta. it should follow aoe3s example of only surrendering when the player agrees to it.
the lack of AI personalities was also disappointing, but it was a beta and I hope to see them at launch.
I agree that AI shouldn’t be able to quite a game just because they want to. Having a pop-up telling them they can’t would be great. Couple that with a creative AI verbal retort in chat could be neat:
I would want AoE4’s default to be AIs that don’t resign. However, maybe allow them to resign via a 105 chat (for all AI at once), or a targeted 105 chat: “105 - 3” for player 3. “105 - 2” for player 2. Conversely, 104 chats to let them resign. “104” for all AI, or “104 - 4” to let just player 4 resign.
And in regard to your topic name, having different AI personalities would be awesome, too, which I’ve suggested before and I’m sure several others. Some as defensive-minded, some offense-minded, early aggressors, turtlers, hide-and-seekers, random builders, organized city builders, etc.
I agree to this suggestion 100%. AOE IV should have multiple personalities for each civs, like in AOE 2 and personalities portraits like in AOE 3.
While I think giving AoEIV personalities like those in AoE3 is a bit too much to ask for there is no reason why they can’t go the AoE2 route with a pool of leaders for each civ instead of -insert difficulty here which for me at least breaks immersion and historical curiosity.
It is small things like this that add up and I keep waiting for them to be addressed without much luck so far.
I do not think, that AoE4 needs “AI personalities”
I would like to see different AI types - defensive, agresive, balanced etc, like in Command and Conquer 3 TW
AI personalities with different strategic tactics - Defensive, Aggressive, Balanced etc. AI personalities has always been part of AoE series. It would be fun to have AI allies or opponents who were able to deliver messages 
I highly support this suggestion 
Having multiple AI personalities for each civs like in Age 2 and Portraits like in Age 3 would be awsome
It was sad to see so much flavor being absent from AoE IV. It’s the little things that made everything so enjoyable and less about optimised gameplay only.
Customization like hometown selection and making it look fancy, earning trivial things like some lantern.
A lot of cool concepts that had the potential to be even better in a new iteration.
The fact that we didn’t even have a color picker at launch speaks volumes about what they wanted to do with the game, they were hellbent on making it an esports title, whereas all other games didn’t focus on competitive play and therefore offered a very colorful PvE experience, with lots of stuff to read and replay.
I am somewhat pessimistic when it comes to the addition of personalities and taunting AI opponents or allies, it means a lot of work for no additional return. If they pulled it off however, I’d be thrilled.
Better say, the older games were balanced about both aspects from the beginning. Tournaments always were part of AoE which is why Microsoft sponsored a 100k tournament for AoE 2 back in 2001 and pro players like Daut or Capoch are active for over 20 years now.
Also, for an esports title, AoE 4 is missing basic features the older games have, such as sharable replays.
Regarding the AI - I also made a topic back in August:
