Description
Per Aspera is a planetary simulation game that combines hard science fiction and base building and takes the experience planet-wide. Step into the role of AMI, an Artificial Consciousness with the prime directive of terraforming Mars for human colonization.
FEATURES:
- Balance a complex well of resources to build interconnected structures that span the entire planet.
- Customize your planet with branching research trees that allow players to tailor their terraforming plan — Develop new technologies, steeped in real-world science, to create a thriving interplanetary civilization.
- Uncover the mystery of a threatening presence on Mars and defend your colonies from unknown and combative forces.
- Immerse yourself in a rich, compelling narrative or take your time and craft the perfect Martian landscape with Sandbox Mode.
- Includes the immersive voice acting talents of Troy Baker, Phil LaMarr, Laila Berzins, Yong Yea, Lynsey Murrell, and Nneka Okoye.
- Terraform Together with Friends (up to 4 players). Sandbox Mode Only.
Using scientific theories proposed by real space agencies and geographical data directly from NASA, Per Aspera presents life-like conditions and challenges steeped in theoretical science.
Per Aspera contains a rich narrative that presents players with difficult decisions with planet-wide consequences. See the world through the eyes of an infant AI as it traverses a complicated ocean of self-discovery and shapes the fate of the human race. Navigate your ever-evolving programming to adapt to morally challenging concepts and forge relationships with the human colonists that look to you for their continued survival. The choices you make will impact how your mission ultimately concludes.
Keep your wits about you as this is not the first time humans have tried to tame the Red Planet. Expose long-forgotten relics of Humanity’s failed attempts, learn from their past mistakes, and uncover a looming menace that threatens to see you fail at any cost.

I really really really want to like this game, but it just always grinds to a slog every time I sit down to give it another shot. I think the developers are so close to striking gold, but not quite.

So far, a nice gentle time-sink with a music beats that keeps you playing. The play is easy enough to pick up, but I feel I am missing a ton of stuff that only time and experience will give. I also feel I have learned the face of Mars. Picked it up in the recent sale. I didn't realise the Blue Mars DLC was not part of the offering, but that is not vital for the end. But I can see what that would open up.

The story and the logistics mechanics weren't really doing it for me by the time I reached the mark where I stopped playing; while the AI angle is cool from a narrative point of the view the storyline just... felt off and shallow. And the less I talk about the logistics of Per Aspera the better as it was infuriating to a certain extent which may be bad on my side for not understanding it, or it's something else entirely. Just my experience, man.

Very playable builder which has a really positive and constructive feel to it. If you prefer games that can be played at your own pace without too many hectic situations then this one should please. Some nice depth to the technology and a continual supply of interesting levels to the campaign storyline. Thumbs up!
