Is there a legacy version you can recommend that is more balanced? I do like most of the changes, and I like the AI not being completely daft like in vanilla, but this has just been an exercise in frustration so far. I want a challenge, but I don't want to feel like I'm being cheated.
And with you saying to not even try to have a coastal city if you aren't going to just spam naval units, it really seems like this mod is just broken to me.
You are playing an experimental beta. Last stable release is from July 2019.
Currently we are testing changes on city defense and in AI diplomacy. The changes in city defense led to lowering archers strength to prevent the unstoppable archer rush tactic.
There were two currents, one asked for weaker archers, the other asked for archers not able to do significant city damage. I'm on the second side.
I still produce archers. You may promote them to medic and hide behind two warriors, so you keep doing damage with the archer while healing your melee. They are less useful than before, but not useless.
And, sorry to debunk your rant, but the game is fairly playable if you know what you are doing. Clearly you do not yet. If every AI is taking on you before time, it's either that you did not care about diplomacy, or the diplomacy changes still need some tweaks.
I'm no masochist, I just downgraded to King difficulty because I enjoy being the leader of the pack. Emperor is still possible to win without serious thought, but it start being tedious for me, with too long-lasting wars for my taste.
I accept the current difficulty so some very skilled players can get their challenge game in deity. I'm no skilled player, so that means Emperor is my ceiling. And I'm happy with that.
PS. Really, the only serious problem with the current beta is how weak coastal cities have become.
