My stance is: I do not think we need new civs, but I would be okay with the adding of new civs IF said new civs would match well in the “medieval era setting” of AoE2.
I have even made a post proposing a new civ called the “Frisians” (aka medieval Dutch peoples) as a possible new civ. Adding new Civs? ---> Discuss!
35 civs is already a lot for a game that originally had only 13 civs…but adding just a few more would be fine by me, just as long as they work out well.
