I didn't fail as quickly as I thought, though. I set the difficulty to Normal and enabled Ironman right away and kind of expected to fail. I started a campaign, ignoring the missions. I've had a medium stressful week of work after me and was a bit overwhelmed, but the combat mechanics and information I had to process were manageable with a cup of coffee by my side. When I first fired up the game, I naturally clicked tutorial first. I've sunk something between 30-40 hours in it now and am in my 4th run (although one run was like 3 minutes long, so). I have enjoyed games such as Stellaris, Mount and Blade Warband, Elite Dangerous, etc, so I guessed Starsector was impossible to fail for me and bought it. I learned about Starsector in through a review of the gaming magazine Gamestar, which I have never read, but it popped up in the news feed of my phone. There's a tr dl with suggestions at the end.
This review is mainly about game difficulty and learning curve.
