Per Aspera has some wonderful storylines that draw you in. Options on how you apply certain prospects towards ultimate terraforming. The graphics aren't the best, but they are not horrible. Game play flows well, sandbox mode is nice for testing options and replay. The workshop where you can try out mods is a great touch as this game lends itself towards player-made mods well, but they disable steam awards. There is some area for growth to be seen, but it's a fine little game with a niche spot.

Nearly perfect terraform Mars game. The story was great, the gameplay loop was engaging. My only feedback is that combat never feels like real threat after the beginning of the story and it of course becomes totally absent after the story is resolved. Furthermore after that your people want not. There's no real reason to keep playing except to fill out the map like I wanted to, it would have been nice if you had to do a bit more to make your people happy once survival needs were satisfied. Lastly, this is such a perfect system it's shame they never tried making more planets to terraform as I could see myself wanting to do it all over again with different geography.

Unlike other space builders it maintains my interest. It is not too hectic, but not too boring, simple to learn and easy to play, and completely bugfree so far. I wish it would show 3D images but I'm also concerned that it may make it too costly and more complicated, so enjoy it the way it is.

This game is really unique and early game is pretty good...but man, does it have some GLARING issues. at $30? ehhh probably not, but when on sale? absolutely. I'll keep it short, the game suffers from a sub-par UI. in late game you're really going to struggle to find specific builds among your web of cities. and god forbid if you use the "Landers" function it introduces you to in the start of the game, You'll think your resources are just fine and find out your main base is starving because it lumps ALL resources together with no way to permanently break them out by "city". secondly, the game fails to provide you with information early enough to save yourself an hour or more of gameplay. Example: you focus on science early instead of rushing the terraforming, this allows you to unlock the "Ice meteor" project. you complete it before you have fully raised the temperature of the planet. Once you have raised the temperature, the water now rises far above where it would have previously, potentially flooding a portion of your base depending on how you expanded. Last but not least, the AI, oh god the AI. having your builders double as the transporters was a choice. I would highly recommend you have your worker hubs on a 1:3, or at least a 1:4 ratio of hubs to buildings, otherwise in late game moving resources around will be a pain. Late game tip: Hyperlanes can be saturated like a road, don't hesitate to create hyperlane "highways" of multiple hyperlanes running in tandem to locations. Don't rely on just 1 connection from place to place.
