I really didn't want to give this a Not Recommended, but due to how things have gone with development i just had to do it... maybe i will be able to recommend it if it can improve or gets a massive price cut
Don't get me wrong, the game is very enjoyable, maybe even to a point where I could consider it good, but it is however an unfinished product. A few very minor bugs are present, the AI is a bit dopey, the enemy scaling is absurd (due to the market system, you can get Gold, a top tier material early on and proceed to completely stomp the first 5 or 6 floors of the dungeon, then suddenly it all comes to a halt on the next floor as enemies can one or two shot your heroes regardless of armor because armor only increases evasion, it doesn't make people more capable of taking damage) the game can have massive lag at times when doing mass item hauling (most common when you want to sell several buckets of iron) and the punishment for doing something wrong can be horrible especially when you don't know why said thing is bad (ie you have to make graves for corpses or they spawn strong ghosts, but now there's an event lategame that can rarely spawn even stronger Zombies for your village to fight off if you didn't build your graveyard a mile away, even high level zombies can spawn potentially adding to the death toll unless your village is well equipped O_O
However, despite all the bad things, I feel like they're more nitpicks that could be ironed out later (if they ever do) the game is strangely satisfying when you do the smallest of things. I felt glad when I got my first town up and running with a constant food supply and with enough production to allow the town to build walls and decor to make them happier, which brings more people in, and eventually Heroes, whom I also got a nice warm feeling from when they moved in, especially a cameo from the fantastic Sips_ :D. When a dungeon level gets cleared there's also that good feeling when you clean all the loot out and equip the village with better items to withstand the ever increasing sieges that want to ruin all your fun. Overall there's just a great feeling I get from getting things done right, it's oddly satisfying to watch all your little people mine out all the stone before converting it into a storage room for your builders so you can continue to build up the town walls to make it harder for the sieges from completely stomping all over all your work so far, and i got a really good chuckle when the nasty hoard of yeti coming in to storm the place is almost completely wiped out before they reach their victims because you built a bridge that serves as the only way in that's completely lined with traps, and watching them set them all off (sadly there's no real animation, but it's still great to watch a big bad yeti get his foot caught in a bear trap and his friend who walked on ahead set off the bamboo shooter, hitting them both as well as anyone else nearby, then the log traps finish off the already wounded, before the villagers team up to pick off any surviving monsters that are likely bleeding from every possible area of their body. Perhaps next time they'll realize that the decaying goblin heads shoved on the pikes outside are a sign that this town is defended)
If you already own a copy go ahead and have a blast directing all your little people to their fates. Grab some mods to fix some of the problems and some of the frustrating elements and you're good to go. If it appears in a bundle with some other things you're interested in, go ahead and give it a go, you might like it. But I would not buy this game through steam now, especially at full price, when there are more options available that either offer more polished development, are cheaper or promise so much more in the future. Gnomoria, Craft the World and Banished are all around the same price but all offer their own quirks and are still being developed regularly or are even finished in the case of Banished.
The main reason I am not recommending this is because the devteam, they released a game which was basically in alpha, but not stating as such, they slowly developed said game over about a year, then dropped it. Now I can perfectly understand their situation, as one who actually browsed the forums, they got too deep into something they shouldn't have, their reputation was on the line, their own personal lives were causing them trouble. They hired another developer but their paycheck would have been so low that they too eventually dropped the project. When the game was left in this dropped state, the steam community went wild, with people buying the game just to give it a negative review, the product tags mostly consisting of "scam" and "abandoned" and the reviews said nothing about the game. The development of the game has since continued, however i would still not buy this game until they can promise to the buyers that they can bring out frequent updates (updates as of late have been very minor and slow, but a v15 is in development to help fix some issues)
So until then, if you have it already, have fun, otherwise it's probably best to stay away unless it's on sale for £3 and you're curious or have nothing better to do for a rainy weekend. Then again, if the devs do get off their butts and finish the game, this could possibly be one of the best entry level Dwarf Fortress clones ever...
