Carradice: I want to like this title. On the fence about it. It might seem to have done everything well. Then, two caveats: One, real time. Although pausable. Two, reviews saying it is repetitive. Reading this, The Long Journey Home comes to mind: it was a mistake. I had not realized how important was using the lander. No option whatsoever to make the landing optionally automatic (maybe with a warning in case there were aliens or ruins). So much emphasis on the lander, even for routine landings, ruined the game for me. I fear the same in this title....
Maybe I can help convince you then:
If you are a scifi nerd (especially works like Foundation and Dune), or enjoy philosophical scifi topics like AI rights and transhumanism, this will be up your alley. And possibly be enough in itself to trump gameplay frustration. I certainly felt my interest in the story and world building was what kept me going.
Gameplay-wise, I am personally garbage at RTSes! Because there is no pause function normally. Yet I found this a lot of fun and - especially after a bunch of upgrades - rewarding. So smash that pause button if you prefer to take time to think tactics!
I wasn't able to play on Hard, but Normal was an enjoyable challenge. Easy mode also exists, if you'd prefer that.
Note that for every chapter, I would select a new ship, which would bring with it a unique gameplay style. I found switching it up like that to be very fun and engaging.
I imagine having a "one true meta" playstyle would likely lead to the game feeling repetitive. That could be where those complaints about repetition come from.
It also never felt like I'd made a stupid descision, both in the choice system and in upgrade purchases. Just be mindful that money and fuel aren't things to be spent willy-nilly, learn to keep some for a rainy day, stuff like that.
Hope that helps a bit.
There is also a demo for the game, so give it a try before you buy!
