In my opinion the Stellaris mod Star Trek New Civilizations is much much better. It actually uses the current version of Stellaris as a base, you can play literally any species in Star Trek, and the mechanics are just great. The game starts in 2150, before the Federation is founded and you (or the AI) actually have to form it as one of the canon founding members, and you can also play as Klingons, Doninion or Borg, all with some unique mechanics. In comparison Star Trek Infinite is not worth it, considering there is a free mod for Stellaris that does almost everything better.

I personally think that this is unlikely, I think we can probably just hire different people for our crew. But I guess we just have to wait a bit more until we find out.

Nonetheless it would certainly be cool if we could do it. And if not we just have to wait for mods to add the crewmembers we want.

I hope you mean the Blue Brixx Star Trek set
