Been playing for years

I’ve been playing this game on and off for two years and it never gets old, and there are plenty of world to play with. If you’re playing with a simple developing biosphere you can terraform a moon/planet in 4-5 days without spending any real money for in-game boosts (called Genesis Points or GP), 2-3 of you do buy these boosts. If you play with a biosphere you can fine tune it’s definitely more of a challenge and terraforming this way might take you 4-5 days with boosts, a week or a little longer without. WATCHING ADS IS COMPLETELY OPTIONAL, YOU WILL NEVER BE FORCED TO WATCH AN AD 🙌🏻 (putting that in all-caps because ad trap games are everywhere these days) but watching the offered ads gives you bonuses to your income and even 1-3 GP sometimes. Watch enough ads and you could have income bonuses for days (literally). Random positive and negative events that can affect your income, structures, organisms, or culture keep you on your toes if you leave the game open, but you don’t have to worry about bad events happening while the game is closed and the terraforming continues when closed, so this game is great for people who don’t want to have to play all the time to succeed. The game can also be paused so you don’t have to worry about letting things go for too long and accidentally destroying your progress. Graphics are pretty and the game runs smoothly. Definitely earned my 5 star rating!

A Console-Level Game On My Phone

I didn't want to like this game, because I've never really been into terraforming or sci-fi games. Terragenesis is an exception to that, and with good reason. This game offers the challenge of having to balance environmental, socio-political, and economic challenges in a way that really makes it come to life. The attention to detail does stand out, with how different levels of Temperature, Pressure, Oxygen, and other things will change the appearance of your planet. The best thing about this game is easily watching your planet change. Watching as the structures and cities you build and all the facilities can change a barren planet like Mars slowly change into a beautiful, thriving planet like Earth, or even watching as Earth slowly decays from a tropical paradise to another copy of Mars. Whats more is the developers aren't greedy with in-game purchases. The difficulty curves can be overcome without the help of Genesis Points (though it is not preferable,) the developers offer frequent ads that in turn boost credit revenue or give the player free Genesis points (Pretty rare for devs to hand out special currency like that) and the ads aren't very intrisive either. The game doesn't require an internet connection so it can be played on the go, the game will continue to change, so if you are playing a volatile world remember to pause when needed, and start on Mars, the easiest planet.

Not happy with the update

I’ve played this game for years off an on and I’ve always loved it. I still do. A while back I had to get rid of it to free up some space and just recently came back to it. I have to say, I’m very disappointed that they’ve added a “forced tutorial”, ie, one that can’t be exited early or avoided altogether. I do appreciate them adding a bit of guidance for new players, but there needs to be an option to skip the tutorial. I have played the game before and don’t need a guide dragging me around and forcing me to do things. It doesn’t help that you can’t cancel actions except by exiting the game and fully closing out of it. With no way to be precise—especially when choosing where to put your cities—it’s really obnoxious to have to close and reopen the game to reselect where you want your first city. That’s to say nothing of not being able to pick where to put your first mine.

The game is great, but it still needs a few tweaks, such as being able to skip the tutorial, and maybe arrows that you can tap to be more precise in location selection (these already exist in the mining interface). Some planets have very little “safe” area to build on—so they aren’t destroyed as the water level rises—so precision is pretty important.
Otherwise, it really is an excellent game that I have had and will continue to have loads of fun playing.
