Starsector is one of my favorite games, and it isn't even done yet. It isn't a suddenly new chunky flavor though. It's one of the older flavors. I've known i've wanted a game like Starsector for a very long time.
The great things about games is they are visual and it's usually easy to grasp what makes them fun. So play the game. Have fun. It's pretty easy to see if you'd like Starsector or not in a video. Personally i love the fine tuning of ship design (or the scrounge whatever you can to make it work early on). I like that combat requires dex, but requires more int. I like that there is several ways to win at combat. I'm excited there is going to be some economy Soon™. I'm excited there is going to be industry too. It's also worth mentioning that the mods are great as well.
I've spent a lot of time extolling the virtues of Starsector to my friends in person, but none of them are super excited about it (not even the one that has the battle tech tabletop games). I was a little surprised. None of them have seen the game play though. They were interested in a pen and paper RPG inspired by it (though i've not finished it because it's hard to emulate a complex game like this in another format(i imagine it's hard to make a game like this in the first place too)). Easily 3/4 of the games i've bought in the last 5 years have been based on video from LPers just playing the game. 1/4 is from a description of the game. For me the description of Starsector was sufficient, but i imagine most people who might like it would need video. So play it, and showcase why you like it.
