Correct me if I'm wrong, but haven't some of the devs commented in interviews how much they enjoyed EB?
Yes I've seen several comments over the years where they have talked about the quality of mods & several times mentioned EB specifically.

I sure as heck hope they have been paying close attention, with the difficulty of modding these newer games it'll be very hard to correct stuff like the miserable version of Seleucids they had in Rome1.
Really looking forward to Successor polyreme battles!
