If you like Factorio or any game with production chains, then this one is right up your alley! If you're looking for ways of releasing your creativity and logical thinking, you won't be disapointed. If you like to challange yourself, you strive to perfection, optimizing everything around you... yeah, you get the point ;) There's nothing hidden from you, rules are plain and simple. Levels (me thinks over 40, with bonus ones!) change the way you approach the puzzle. You can test your design without consequences and you learn by debugging and observing your process. This lets you quickly understand what works and what doesn't.
Recently lots of city builders showed up, mostly in Steam's Early Access, and I never thought this kind of games could be so well polished! It presents important information in clear form, so you are able to plan for the long term. Resources are limited to minimum (coal, wood, steel, food), which lets you focus on other (very important) aspects, like heat, tech tree, discontent and hope, scouting or choosing appropriate laws. What is fascinating, that none of those features is excessively overpumped, each plays a significant role in your survival. And, I can't state it enough, it's incredibly well balanced! The scenarios are very well designed, to give us the feeling of incoming doom and warn us in advance. That's also the reason why I don't think there's a room for a Sandbox mode - it just wouldn't work! Random encounters? It would be too RNG, which is not quite the soul of this game. But... scenario editor? Letting fans create the rules and share their vision of Frostpunk apocalypse is imho the next step and correct approach. That would make this game immortal.
