Okay so, I'm not exactly sure if i should upvote or downvote it, because both would be true.
First of all the good part. The first 10 hours of the game or so, maybe a little bit less, 8 hours - seem magical, astounding and absolutely amazing. It reminds you of old masterpieces - dungeon keeper, Knights and Merchants, even survival games. It's all great - I mean you can dig, create stuff, decorate it, smash monsters, level gnomes up, craft, you can craft a lot. More advanced crafting requires gnomes with specific skills. So the idea's great, you unlock more and more recipes by crafting newly unlocked stuff, the world seems a better place with this game around.
And then you get to midgame.
You start lacking resourses, especially the most important resourse ingame - iron, which is non-renewable. You start going to edges of the map, which takes gnomes forever to just reach, not to mention they prefer spending their time doing something you didn't really even ask them to do. Even with teleportation to the right place, you just no longer control them, the AI gets dumber the more you build and explore, while gnomes never get faster, nor you get a huge army of them. By midgame you require at least 5 times the amount of gnomes you have!
The crafting turns into hell, because you need to unlock 5-10-15 more levels to reach a needed crafting level by crafting stuff you clearly do not need need in huge amounts: like 50 book cases, or 15 stone statues. You exhaust your resourses on trash, just to get over it. You also got to build that trash, which requires you to use pretty inconvinient system of placing the newly crafted item into one of 20 fast access slots, which in midgame are already filled out with important things like spells, food, walls, bridges etc. And then restore the previous one the same way.
By that time you get the feeling that you'd rather stare at the wall doing nothing, than play on.
Awful late game balance and AI management completely kills the game.
But at least you can enjoy first 8-12 hours.
