EDIT: I've tried three times to get to the end game, and I just cannot get over the constant need to get rid of the waste products from the cities, by that time I've already built several factories to help supply stuff, but when the waste products get up into the hundreds, I just get super overwhelmed. Still, great game, i just cannot for the life of me hit that 1,000,000 Population threshold because of the damn waste. Hoping a mod comes out that allows me to at least significantly reduce it, a way to just launch junk into space, or some advanced difficulty setting. If you love Satisfactory, Factorio, Civilization, and City Builders. This is the game for you The game does get VERY overwhelming in the end game, so plan ahead and dont keep the triple speed button on for too long. Best thing I can tell you is: Cities will eventually not need previously needed mats, and for gods sake dont make carbon tubes in a city far from the poles, You're Welcome First Playthrough will ALWAYS be rough, but when you do the second one, you'll have all the foresight you'll need, and it will be GLORIOUS. GREAT GAME Edit: Got to the late game.... its VERY VERY HARD to keep your cities constantly supplied, even when the city growth is set to VERY EASY. I will be waiting for a mod to come out to help with this before I continue playing....
I bought this game to serve as an aid while i waited for Transport Fever 3. I thought i would get a simplistic "move the stuff from one place to another, fill the progress bar" game but this game really surprised me with how good it is. I highly recommend this game in its own right, not just as a timesink while waiting for an anticipated sequel! its progresion and what i will call a story (i suppose because it is in fact a storyline!) unfolds layers of complexity quite nicely and i never felt bored by the progression. When a city grew too large and started to decline i realised i couldn't feed it resources quickly enough and had to entirely re-think how i deliver the resources. This type of evolution in how problems are best solved leads to a satisfying sense of accomplishment. There are downsides of the game. In its current state i can't tell whether i really am running out of water, or whether there is a bug in the game save/load system - if i save a game while i have built a full stockpile of water i can return to that save game later and the water stockpile will very quickly be emptied. I can't tell whether i have a bad logistics path or whether the loading of the game doesn't work right (and the water pumps aren't actually pumping for a couple of minutes after a game load) The other downside i'll mention is that while the progression is good, it feels a little uninspired for the devs to have made the decision to have most of the objectives be a simple "reach a higher total population". At level 23 i'm introduced to another end game resource i have to factor in to my supply chains, and this is great - a new challenge! but the objective to reach level 24 is to have 1 million population. I would like to have seen more of the levels milestones be related to producing the new resource, or completing terraforming targets. On balance, and in summary - i highly recommend this game!
Wow! I don't often write Steam reviews, but this game is an underappreciated gem that deserves much more highlight. I would describe this game as Transport Tycoon meets Factorio with a terraforming theme. Where you as a player are really the one driving the terraforming to the benefit of your cities. The game is really well balanced and leaves many annoying aspects (like managing electricity) aside, to let you focus on the more fun elements of managing logistics and builds. It has some very novel gaming mechanics. For example, the water dynamics are done very well and very gradually change your game world with new opportunities and challenges. Highly recommended, this developer deserves much more spotlight!
This is really quite a phenomenal and cathartic game for logistics nerds. It's incredibly simplistic, but it only uses that to build a large and fun scale and complexity through that. It's not as heavy as Factorio, but it's by no means less for it and is quite easy to pick up. You get ores, you make products, you turn products into more products. You feed the city with those products. Those cities make basic waste of slightly less than what you supplied them, and you figure out how to recycle them back into the production chain. You do this with drone ports that just pick up and ferry resources within their range. This simplifies, but doesn't eliminate, a lot of micromanagement. All of this is mostly a logistics problem and production location. 3 ore turns into 1 steel, don't transport the ore. You need to carry a ton of resources across the entire planet. And eventually need to connect all three cities across the planet to each other in order to supply each other with the higher tier resources to grow them bigger. 1 million is the goal, and it's not the simplest one to accomplish. You are in just a map view, not a character, so you have full freedom around the planet. Everything can be freely and instantly constructed and demolished to inventory at a whim once you produce it in the first place. Every building or selection of them can be literally cut, copy, and pasted around, or click-dragged around easily. And you'll need it, because the planet changes. Whether it's the cities you're growing or the oceans and jungles you're creating. Both of these offer profoundly cathartic reasoning to play. The cities scale but don't get too out of control, in size or resource usage. At the same time, the urban planning I'm forced to do around the massive growing river down the middle of one of my cities, or stopping their expansion into a O2 critical Jungle biome, is a marginally annoying but ultimately fun and unique experience to play-through. It's nice as well that most of the population of cities are moved around to other parts of the city when they are flooded. Not all of them, but the city also just ends up developing denser in more stable areas. It feels bad at first, but once you realize it didn't actually set you back much, you can just accept it and think about how you want to work with it. All of which offer such fun and creative world-building and role-playing. And world-building is the name of the game. The terraforming aspect is simple, but this isn't to its fault either. It scales to a huge hex-tiled planet with varying heights and water availability and rivers that naturally create different climate regions on your unique planet. Seeing your planet naturally green and where various types of trees and biomes naturally develop is really cathartic. You do need to seed a lot of these regions with your own produced trees, but they do grow very quickly and exponentially on their own beyond that in their viable areas. My main complaint is I wish this game had more types of vegetation options and oceanic biomes that formed. It'd be really cool to see some of that form on your planet. I have some cool atoll/reefs that ended up forming from some craters I'd like to see coral form on. There's also a spoiler thing that happens partway into the game that I wish would return again and become relevant. In the end though, very worth a good playthrough. Your industrial areas will be flooded. You can literally cut and paste the entire thing somewhere else. It's more important how you connect it and develop new areas for it. And where you source it to not have an ocean flood it. Or fight back the 90m tall ocean with tons of dam pumps while you mine out the iron/aluminum there.
Solid title. Very well designed randomized worlds with a great visual aesthetic. For those like me coming from Factorio, the depth of this game is more shallow and less polished. This is mostly a good thing and It still provides about 100 hours of fun so it is well worth the price. It is well differentiated from other automation games. Plan b focuses on environmental engineering and there is plenty to build. Only negatives are an over-emphasis on rebuilding and rebalancing due to environmental changes / tech requirements. The first playthrough will have some tedious and repetitive moments. There were a few small UI quirks like not having build hotkeys and terrain leveling being a total bearcat to master. I definitely sunk over several hours using trial and error to make new waterways and not drown my cites. This is due to an amazing mechanic of the water being very complex, but it's very tedious to control because it responds slowly and unpredictably. Can't wait for a sequel or future title from the dev.
