In Age of Mythology Retold, you have an option to “Custom select shuffle” where you can pick a group of civs to have in a shuffle/random selection. I would love to see this in AoE IV because I’m always torn on which civ to pick out of a handful, but not ready to commit to full shuffle yet. So the option would let me pick 2-3 and then would shuffle through them for me instead of having to lock in on one each time.
