Seems you have done it only for your own pops ?
You need to do it for the whole galaxy ... don't forget to reduce the strength of the crisis also , as the galaxy will have a lot fewer production ...
POP GROWTH
... for me that is the biggest problem from the Stellaris Game , even now worse than before. As you now need houses, entertainment and jobs . POP growth as it is now is boring, because more pops didn't offer more variation of strategic play only senseless clicking AND MOST IMPORTANT , you don't care for them in any situation as it is mass ware !
Even at midgame you are limited to build only buildings with 10 jobs , as the next game design error is , that you could only build 16 buildings AND THAT doesn't even keep in account, how large the planet is ...
MORE isn't better, it only means MORE from the same ...
so the game really needs AN OPTION (all who don't agree COULD YOU READ and UNDERSTAND , what an OPTION mean ?),
when you start a game , it should be possible to chose ,
which modifier you want from PLUS 90% to MINUS 90% pop growth for your universe.
Also to make more strategic decisions possible and make it possible to build buildings with only 1 job , how many buildings are possible should depend on DISTRICT SIZE and not that strange 16 slots always !
I am using a mod which allows , I think 32 buildings and my own mod for minus 90% galaxy wide pop growth ... THE GAME HAS NOW A LOT MORE STRATEGIC decisions to offer, the original game is unplayable for me, special after mid game, when all planets are already full and the same ...
BUT YES AGREE, with that change , the game needs more DIFFERENT GAMEPLAY , like spies , ground exploration , ground battles ...
but even without them it is more fun, for strategic minded players !
When you are playing right , even after 100 years you could have a large home world ...
and I AM PLAYING WITH MINUS 100% GROWTH ...
Now all that technology and BUILDINGS for pop growth MAKES SENSE, never used it in normal games ...
And to enjoy the game and create different specializations for your planets you need for sure more than 16 buildings ...
I am using this two MODS ...
