I don't think Star Trek works as grand strategy, the lore is too restrictive to really allow for both player choice and the "star trek" feel. ST would be best as an action/adventure game, I think. Basically, fly around to different planets with different themed adventures while building crew relationships just like the shows. Resurgence was supposed to be something along those lines, but it looks disappointing.
I highly recommend Resurgence, but ONLY for the story. It was a nice little Star Trek adventure, but the game around it is lackluster and buggy. Some of the set pieces are gorgeous though.
Yeah, the strength of Star Trek would better fit an adventure. But maybe they are Mixing elements into the game or add a nice campaign.
If it really comes down to being just a Stellaris with Star Trek skins, i would be a little disappointed. There the main focus lies on the planets, ships and captains are totally replaceable.
