I won't pretend to like the new ages system. I don't. But I can live with it if I'm given agency over how it affects my gameplay. As it stands, I have zero desire to invest in any war or diplomatic efforts because I know they will be arbitrarily wiped from the board and I'll be quickly forced down some other narrow path regardless of how I feel about that.
In my first game, I was really enjoying new mechanics and absolutely loving some of the new systems I had available. I had a roller-coaster alliance form between my civ and Lafayette. Lafayette had two occupied settlements that I was hell-bent on freeing. I was leveraging diplomacy with nearby-city states to assist in the war effort, spending a few turns building fortifications around the contested areas and setting up my military for a swift and smooth operation. You see, I was going to make a forever-friend here. I was going to give the Lafayette his settlements back and we were going to do glorious things together. I began my assault.
And then the screen faded to black, I was told to pick between two culture-focused civs that I DID NOT want to play, all of my units were converted into basic warrior types as well and piled into my capital, and all of my diplomatic history was erased. All in one single turn.
I immediately quit playing. What would be the point? If all progress is reset and major decisions are made for you, why bother playing?
I fervently hope that they completely dismantle the ages system but if they have to keep the ages system, which breaks continuity and drains the fun out of the emergent narrative, at least let me decide where I go next. Let me decide WHEN I go. Let me play until I'm not having fun anymore. DON'T press the reset button when I'm just getting to the good stuff.
