In AoM, I take most joy playing some random maps with my friend, mostly playing conquest. But after playing a while against each other and together against bots, I have decided that I wanted to create my own map to play on. But while the map editor is really well made, creating the gameplay around it is not self explanatory at all. There are several things I'd like to make, I have not figured out and couldn't find online. Issues are as following:

1. I placed multiple empty settlements. Amongst those settlements, I'd like to pick specific ones players and bots randomly spawn in. In online games, settlements often come in a cluster of 3 which I did as well. But the spawn seems random, so I'd also like to select settlements that are "starter" settlements to randomly spawn in. As a plus, I might want that some settlements don't spawn if there aren't that many players around (6 for 2 players but maybe 8 or 12 for 4 players?).
   
   
2. I'd like to place unaffiliated but hostile buildings around the map in a specific theme. I know how to place Sentry Towers and how to upgrade them, but the Gaia towers upgrade to an Egyptian theme. I'd like to have a greek theme without the tower being part of a player (by default player 1 is greek, but that would make it an owned tower, right?)
   
   
3. I also would like to play it in different modes. So far I've seen you can play those as scenarios, but that blocks the option to play it in a specifc mode (conquest, supremacy, etc.). Is there a way to work around that?

Thank you in advance and have a Happy New Year!
