Star Traders: Frontiers is actually a very nice game. Spent a lot of time in it some time ago, and it has since grew a lot because the devs are fantastic and kept adding free patches. and content almost every single week for almost 2 years after launch. It's surely worth a brand new playthrough now.
Look forward to their new game.
As for the topic, I think it's neither a homage or ip violation. It's just a game with the word "Frontiers" in the title. And while it's called Star Traders, trading is but one of the many things you can do.
