Calling dusty post-apocalyptic city builders a trend is probably a stretch, but not by much. I suppose it's a natural extension of the post-2000s explosion of the survival sim from "literally about 3 ever made" to "does your tetris remake really need the hunger meter". Games like Against The Storm porting over the roguelike element as well certainly suggest it. In my head, that's probably why New Cycle hangs out more with Endzone Dash A World Apart, and Surviving The Aftermath. It's more a traditional building game than a punishing test to be retaken, or the intense "survive the ordeal" narrative of Frostpunk, despite the superficial similarity that your town expects to be ravaged by scorching solar flares.
But it might also be because after playing it more than I really wanted to, New Cycle matches those two peers by leaving me with a vague feeling of disappointment. I'm just not sure what it really has to say.
