I similarly get bored of Skylines as soon as the game starts handing you near-infinite money. Making something aesthetically pleasing is only so interesting to me - I want the challenge of constraints.
I actually have a similar problem with the Tropico remakes. Tropico 1 was hard. You could not survive a mission without dipping into the dictator toolsets. So striking a constant balance between economics and human rights was an interesting challenge. (It also made for a much more biting satire). The games since 3 are still pleasant city-builders in their own rights, but make it a bit too easy to win on the straight and narrow.
