Yes, TerraGenesis is as cool as it sounds, if not cooler. While apps across TerraGenesis Store get simpler, and frankly, more boring, this app will bring life back to your game list. Literally! TerraGenesis truly has the depth of a computer game, and it runs great. It is very realistic and everything generates very slowly and visually so that you can truly see your planet, whether it be in our solar system, on the moons of the gas giants, dwarf planets, or many many other options (at least thirdy, each with its own intense description, plus randomly generated planets). It is visually appealing, and very high quality.
This being said, the game may not be for everybody. You have to have SOME kind of interest in Geology or Astronomy to truly fall head over heels for TerraGenesis. It’s still a great building and idle app if you don’t, but you may not be as fanatical about it as me. Also, as I said, it is mostly an idle app. You can have the moon’s atmosphere pressurizing in your pocket, but while on TerraGenesis there isn’t a WHOLE lot to do other than manage everything for about 10-20 minutes a couple times a day. You will not be on TerraGenesis all day, but TerraGenesis will be on all day. Keep this in mind.
Overall, if you’re thinking “this looks pretty cool”, GET IT. Seriously. It is NOT pay to play, it’s not cheap, it’s not buggy, it’s not boring, but it is sexy. Do it.
