Greetings fellow SCII enthusiast! I'm glad this caught your attention. I absolutely love SCII, and have played through it multiple times. More than 10, easily. Each time doing things a little differently. Selling humans to the Druuge was fun.
Anyway, thank you for your interest. I'm not sure how playable this game is now. I've gone back to it, years after finishing it, and it's extremely unbalanced. Like, horrendously bad. There's no balancing at all! I thought I was being super clever with so many different little things, for example hiding stats unless your science or whatever was high enough - the bit about spies was kinda broken. The game is basically either stupidly hard and unintuitive, or ridiculously easy (science is way too powerful). And if you do too well, the game punishes you with surprise catastrophes! And if you do super badly, it surprises you with bonus events to help you. This was my attempt at "balancing" it.
The resource management came from watching Battlestar Galactica, but given that I love SCII, I had to use that scenario. Lots of fun.
It's nice to read that you also loved the game so much you were writing your own follow-up scenarios. Super cool. Did you ever play Star Control 3? I finished it twice, but I didn't like it much. And then I played the newer recent Star Control game, but I didn't like it at all! It just didn't land right.
The original creators are working on a true sequel, with a different name but the same races. Are you following that? I forget the name they use. Free Stars? By Pistol Shrimp Games.
