brilliant dark and moody cyberpunk city builder is my kind of cosy game—and for less than $7 you might as well see if it's yours too

Dystopika is a pretty cool sandbox experience, I wouldn't call it a city builder in the traditional sense. There is no management gameplay or progression, you just plop different assets to make cool cities and scenes.

It's a lot of fun if you like the cyberpunk aesthetic. That being said, when I last played it I ran into the issue that there weren't enough assets for variety (it does have a dynamic size system).
