Ooh late reply. I don't get on itch too often.
As for your game, I didn't play real long (I'm easily distracted), so I can't offer much feedback, but it's in one of my many folders as something to return to. Like a little digital shrine to dig up in the future, with other cool ideas I breezed by.
It was just great to see a game idea similar to my own narrative roleplay idea. I would have loved for an SC sequel to follow that idea, rather than rehash all the elements of the original. SCII is a singular thing, it evolved from SCI, but it's not something I want to see repeated slavishly. Your game idea is at least taking off in another trajectory, so kudos. And yeah, it has Galactica vibes, which I also find very appropriate for a sequel to a sequel that focuses so much on resource and strength gathering in a desperate atmosphere.
Boring story about SCIII: I got my first PC around when the demo for III came out (PC gamer demo CD), and it was a baffling thing to encounter. The full game had a nice treatment in PC Gamer, IIRC, and had what appeared to be claymation'd talking heads. The writeup didn't give me much of a clue about the game, and the demo was the Super-Melee mode, and it frankly seemed primitive compared to the FPS and Star Wars flight sim games I was more into at the time. Gimme this in a first person cockpit, I thought (as if that would work).
So I never played SCIII, and I may never. But SCII? I'll return to it one of these days, though my One Golden Runthrough will remain the core memory of the game: after losing my first game, I started over and played it meticulously, keeping notes and everything, getting the ending I wanted. What an experience, and to be honest, the first failure made the second play so much better.
