I've been on latest beta 1.4.2 for like 100-200 hours now and I have some feedback for it. Im at day 2545, im lvl 21 and aged 60 something and my kids are all grown up
Its been a lot of fun but it does feel never-ending.
The main culprit imo is the fact that my faction (valadian) continually has had 2-3 wars going at the same time most of the game. Its very hard to make any progress when its like this. One suggestion to perhaps alleviate this problem a little would be to allow players to spend more influence (if they wanted) on certain votes, such as war votes. Being only allowed to spend 100 influence means its virtually impossible to affect the outcome on whether we go to war or make peace. Personally, I think the AI should factor in whether we are already at war, and if we are, then they should be much less inclined to sustain or start another war. Also in a similar vein, I feel like the sheer scale of the game - specifically, all the neutral factions and the number of parties each faction inevitably can have, has a detrimental effect on the overall flow of the game. For example, in order to simply move across the map in my game as it is currently, I would have to kill 10's of thousands of troops.
A better example would be when I had something like 30+ kuziat prisoners in my town seonopa (i think its called) and yet I still was not able to leave the city in order to go north to Osor (my other city) without having to swiftly turn back around because seonopa was getting seiged again by yet
another 1000+ army. After awhile the battles feel like a bit of a chore simply because they feel endless and your victories fruitless.
I do encourage the game to try and become as difficult as possible (when the player has selected realistic options and good AI combat etc), but I would much prefer it if the battles were simply harder but less frequent - so quality over quantity in other words.
