Frostpunk is made by my favorite game studio and I love the genre and all their other games, but I really did not enjoy it. Some reviews mention that the scenarios have such small margins that unless you do things in a specific way, it’s very unlikely you will beat them. I agree with that to a certain extent, but it feels like there’s something else to it too. It’s been years since I played, but the tech tree felt interesting but like it wasn’t properly enmeshed with the gameplay and struggles with an obvious winning strategy that limits your feasible options.
I definitely second don’t start together as being the best way to play. I also heavily edit the settings so that it’s not as punishing as the default. It makes the game experience feel a little more open world and less full-time grind.
