Two years ago I made a list of civs by campaign appearances, since there was a pattern to include civs with a lot of appearances in other campaigns. While the pattern is now less prevalent, I thought it was still a fun topic to revisit
Kannadigas
- Almeida 4
- Prithviraj 2, 3, 5
- Rajendra 1, 3
- Devapala 1, 2, 4, 5
Aragonese
- Almeida 1
- El Cid 3 and 5
- Bapheus
Mamluks/Egyptians (honestly this civ is questionable, but I could see it happening unlike civs like Sosso)
- Longshanks 2
- Tamerlane 5
- Almeida 5
- Saladin 1
you could also argue that Saladin should be an Egyptian campaign)
Ghurids/Afghans
- Tamar 5
- Prithviraj 1, 4, 5
- Babur 2, 3
- Ismail 4
Could represent Afghans in Babur 1, Bukhara
Crusaders/Outremer (I mean, we got Romans already, would it be that ridiculous to get them?)
- Saladin, all scenarios
- Barbarossa 5, 6
- Thoros 3, 4, 5
- Longshanks 2
Scythians (Alans and Sogdians included)
- Bukhara

Could replace Cumans by Alans in Tamar 1
Normans (ew)
- Hastings
- Hautevilles 1-4
- Bari 3-5
Aragonese
- Almeida 1
- El Cid 3 and 5
- Bapheus
Moors
- El Cid 2, 3, 4, 5
- Tours
Possible replacement of some of the players of the Berber campaign
Venetians
- Sforza 1,4,5
- Barbarrosa 4
- Lepanto, maybe?
Turkomans/Azeris
- Ismail, all scenarios
- Tamar 3, 5

Tlaxcala
- All of Montezuma but scenario 1
Wari/Chanka

- Sundjata, all scenarios but scenario 2.

- Gengis Khan 1, 2
Sinhalese
- Rajendra 2, 3
