Hello all,
after many years I was stunned, that such a vibrant Starcon community exists ! GREAT ... StarconI and II were one of the best games I ever played, and yes, my both sons (16+23) play them alike ! They love it ! The story dense, the threads twingled, the races individually lovely - except the dynarri.. Ok, enough said, just tell me, where to buy the next game ? 
Welcome to the community. It's great that your sons also enjoy Star Control. I remember my dad playing Star Control 1 on his DOS PC when I was a kid and I watched him play the combat portions of the game. Eventually, me and my brothers started to play it and we got hooked. Since then, we started to play other games and deep down inside, we never forgot about Star Control.
Did you get a chance to write an e-mail to Alex Ness showing support for a new Star Control game?
Regarding that "next game", I wouldn't play it at all. I played it and I regretted it. The characters were puppets with limited motion and colours, unbalanced ships, really bad voice acting and I refuse to believe that the Precursors are a bunch of hippo-like things. It's non-canon, and even TFB don't consider it canon. TFB had nothing to do with that game. After making SC2, Accolade wanted them to make another right away after working overtime just to wrap up SC2, so they chose Legend to do it without TFB's help. Here's a video of some gameplay:
