I know this topic had a pretty lengthy discussion when this was brought up on the insider program, but since EL2 is now released I feel this topic should be posted here.
Pretty much after about 50-70 turns it feels way to easy to snowball. district and by extension foundation can be spammed because it very easy to get a ton of production and influence, improvements further pushes the snowballing, etc. Meanwhile food in generally not that important.
I'm going going to repost what I said in the past and in my review.
- Districts should primarily or only provide jobs. That means farms give citizen jobs, works give artisan jobs, etc. Communal Habitations should be changed to instead provide a new city mechanic which would be housing. So in theory you want to make sure your pop both has jobs to work and a house to live in. Seems reasonable. This also makes food way more important.
2 Cities should have a limit of how many districts they can have that is either tied to the cities total population or add a new system where you can invest influence in a city to increase the district limit for said city.
- Improvements should have more of a focus on buffing job yields or a getting mix on what they do with a little bit lower yields. No more +25 production on a blasting furnace in era 2.
bonus point: this was not my idea, but I saw it once and I like the general idea of this. Have building districts/improvements cost industry and have military units cost "manpower". Then change Keeps to pretty much do that they do now, but add in a manpower increase. Then you can take my idea for having district providing jobs and add a new job which grants "manpower".
I really think these idea would make the economy aspect so much better then just mindless spam and snowball. Might even want to consider adding approval penalties to distracts.
