Also yeah, optimizing is required here in order to play on default difficulty, that's a given. That's why most of us here for, in fact.
Except there's not enough tactical depth. Cover is simplistic and combat area design is atrociously bad. Positioning is more of a puzzle and a case of trial and error than anything else. What you have is build depth and story/quest depth but that's wasted in a party-based and ranged-weapons-based system.
The story is disappointing compared to AoD. The old-world locations were fascinating with their mysteries and it was really satisfying to get through them despite (or maybe because of) metagaming. What we have instead is shitty journal in the lander (though it's a low point, others are somewhat more interesting). Without a historical setting, the authors are out of their depth.
When the subjects were history and the Mythos, ITS' games worked just fine. The hard scifi setting is appropriately designed but they haven't done anything interesting with it. Aliens
are almost-human bipedals, aka the dreaded 'rubber forehead aliens' (semi-spoiler, Vince talked about it a long while ago around the time the game was released in EA). Rocketry and orbital mechanics and even life support are a very interesting and complex subject, just play KSP RP-1+Kerbalism or even plain KSP or SimpleRockets/Juno, or watch a video by the Pressure-Fed Astronaut.
Edit: if you want to see a good approach at writing a first contact with alien species story, read S. Lem's Eden.
Honestly in terms of colony ship settings and stories that can be told even the visual novel by the proto-SJW woman had more interesting writing (as long as you can stomach weeb-SJW shit) and exploration of the human condition. The Golden Age of Science-Fiction had too many stories that could be adapted/synthesized especially by writers underappreciated in mass culture. Could've made the factions, locations and side quests borrow from Cordwainer Smith or even PKD's (still underappreciated!) paranoid Cold War style with a large dose of
delusions of reference that was his specialty. Instead they've done nothing at all of the sort, and the story is almost perfunctory.
Still worth buying twice over.
