There was a Trade Wars inspired game 25 yrs ago called "Black Nova Traders" that was a whole lot of fun. The original author is embarking on a v2 after a quarter century since the first release. You might find it interesting to see if yours and his vision align and work together[1]. All good if not, I'll keep an eye on your project as I love Trade Wars inspired games.
For fun over the weekend I started an ambitious project of creating a "pocket size" space trading game, inspired by a classic BBS door game called Trade Wars that I really loved as a kid. I'm keeping a development log to keep myself motivated and wrote the first post about it here https://jarv.org/posts/stardewar-v01/.
