I mentioned this on the Game mode Speculation Thread but it seems that there is evidence that we might get a free Pirates scenario sometime, it could be in the next update in October. Happy Birthday to me!
Anyway during the June update we got a religion faith rework as well as they added zombies and aliens to Red Death. Soon after we got Ethiopia dealing who is religious and Secret Societies which came with cultists and vampires.
Fast forward to August and that update came with a rework to amenities and the tech/civic tree shuffle. Then in September we got Byzantium who got a unique EC and Gaul which unlocks Apprenticeship when an Oppdium is built (can be good for the game mode).
If the October update comes with a free multiplayer Pirate Scenario what are the chances it might be a hint to the upcoming 4th DLC or any other?
If we combine that with the MoorTires name it seems a little obvious maybe they are leaning into a North African civ with Berbers/Morocco.
Then again Lisbon's suzerain ability prevents traders from being pillaged over water and the Moors did control Iberia for a while.
Either way I was kind of expecting it to be one of those two (Portugal or North African civ) but with the addition of the possible Pirates scenario, it just all seems to coincide together.
I don't know if they would directly have a pirate themed civ in the base game though considering that's what we would get in the scenario.
