“This game turned out to be a really enjoyable surprise. If you like logistics and base building but want something more chill than the usual heavy hitters, this one fits that vibe really well. The UI is clean and easy…”

“The game certainly has potential, and the use of a 3D globe (instead of a 2d map like other factory/logistics games) is cool. Also seeing the world slowly change and evolve as you develop it is very interesting. The…”
“It's quite pretty, and watching the very nicely generated planet slowly change as you progress is very nice, but the actual gameplay isn't made up of particularly engaging puzzles, and setting up logistics is…”

“AWSOME!! I love the game graphics and how it simulates mars getting terraformed! Its also one of those games where it will take a long time to complete so enjoy!”
“This is a great cozy Transport Tycoon-style game but with charming graphics and sci-fi setting. You have to adapt your transport system constantly as your cities grow and the planet gets wetter. Just the right amount of…”

“Great factory game to sink a good couple hours into its not too crazy or hard I do recommend first play through do infinite ore veins so you understand all machanic's”
“Good Factory sim for starters. Not too complicated and a good way to learn how to balance. I wish it was longer and it's really cool to watch the world terraform in real time. Devs should make a DLC that ties in with…”

“Enjoyable game, worth the price. I love the terraforming genre and this is one of the best.”
“Very nice and cosy game! Really fits well in the factory game genre. It has its own personnality and its own mechanic. It's a bit smaller with more arcade-ish mechanics but the game really makes them its own and fun. I…”
“Great game, well worth the money. I highly recommend this for people who like factory type games, or games with resource management. It's really fun to watch your planet evolve over time.”

“Not a bad idea, and it's fun for most of the game, but late game is broken. The developer posts odd stuff on discussions, like telling people the game does not work towards the end-game and you have to cheese it. You're…”

“Not a bad game, has its highlights - seeing terraforming progress with growing forests is cool. What is not cool is actual gameplay - with very little control over logistics as the main part of it are autonomous drones…”
“Its interesting. Im not very good at it so im getting a bit furstrated after about 30 minutes of play but I keep coming back to try. I think if you like factory builders then you will enjoy it.”
“game is a bit of casual simcitying on default difficulty, and does not really make me want to replay it on higher difficulties since there are no actually impressive gameplay elements”

“Not recommended. There is basically zero tutorial and the game is not intuitive at all. Add to this the fact that a body of water larger than the baltic sea "moves" across the map. sorry thats just broken logic. You…”

“I really like this game, it's an interesting concept done fairly well. Now here comes the BUT: do not buy it if you have similar life circumstances to me. I'm in my mid-thirties with a family so the only time I usually get to play video games is late in the evening after a long…”

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…”

Pros: the water system…”
