Absolute beast of a game. Makes you realize this is what the game industry should look nowadays, complex games that favor player creativity and simulation of real life.
You can't really write a review on everything on it, but believe me when I tell you that once you get pass the UI (which is frankly terrible, but a price you pay to get to the diamond inside this game) you will discover a world so vast, so rich, so alive and full of posibilities. Words fail to describe the absolute liberty you have in this game, and the complete randomness in which your story will shape.
And example from a fortress I ran a couple of months ago: Everything started nice, made my dwellings by excavating on the floor because I couldn't find a mountain that was sturdy enough. Anyway, after a couple of seasons ingame (2-3 years) I indirectly angered the local rhesus macaque monkey population, which resulted in an invassion by close to 50 monkeys to my hold. What followed was a massacre to the monkey population, with dwarves using them as flails when alive, and then as axes when they splintered their bodies, and finally throwable objects once their limbs got removed. After that, two or three seasons later I got invaded AGAIN but this time by gray langurs. Another massacre ensued, with my dwarfs getting enough bone and leather to craft wealth for the traders to buy.
And then I got invaded by a collection of weremonkey men and werecamel men with dresses full of coins as weapons that completely fucked up my hold and bit the few survivors, guaranteeing a breakout of werecamels and weremonkeys in the zone for generations. And at that point I had to restart.

I don't joke when I say thins: You are missing out your favorite game by not playing this.
