Planetbase - Planetbase 2 - Dev Update 03 - Steam News
This 3rd update includes the Geothermal Plant, Bio Dome, Processing Plant, Gym and more.

I have 200+ hours in the original Planetbase and 100% achievements, so I am pretty biased, but I love the relative simplicity (by the standard of most city-builders) combined with the sci-fi themes and survival mechanics (albeit starting from the mid-game, the survival mechanics are not that important) of the original game.
I always wished there were more compelling late game expansions mechanics and buildings in the original. Planetbase 2 looks to be shaping up as the sequel we need 10 years after the releases of the original.
