it good
Great game. Love playing survival mode. The campaign wasn't for me.
I really enjoy this game. It has its flaws for sure, but I think embracing the tactical nature presented by those flaws is important to enjoying the game. For instance, you cannot save and load. Every choice you make is permanent, and if you lose you have to start over entirely. Annoying, yes. But, I also enjoy it because it rewards you for knowing what you're doing. If you play properly, youll never encounter this being an issue. I haven't at least. In the skill tree, if you spec incorrectly you can and will get softlocked and be unable to progress. This is also annoying, but it makes me really think about what I'm going to unlock. Like, is it really worth it to use research points on 30% extra food from hunter huts? Probably not. But an extra 200 gold every day? That would let me build 3 hunter huts, so obviously I pick that. New unit that helps me hold and clear areas faster, or making windmills produce extra energy? If I clear more area, I can build more mills. You have to approach this game with a very specific mindset to enjoy it, and you have to embrace the punishment. I'd also recommend not caring about score on your first go arounds, since it literally means nothing.
