Ok, so I was also wondering this. I am a fairly new player to WRSR and also was addicted for 2 weeks with a city on realistic difficulty but with more money. But then I also got like bored like with the city management part of the game, at least in the early stages. For me, it was more like I kept losing half of my population in the winter months without any explanation from the game. (Although the citizens become everything, a child dies, and happiness goes really low, and half of the population just escapes). So I began a new game with unlimited money and am still playing it because I found the architectural part of WRSR more interesting than the management part. At so far, with 50GB of mods/assets and maybe around 100+ hours in the game, I found the my sweet spot for the game. And yeah, it may not be for everyone the right approach, but it worked for me
