Endless Sky seemed like a nice refresh when I tried it a few years ago, did a few initial quest lines.

It was interesting how the different faction technologies had different power/mass/volume/hardpoint production and consumption ratios, so there was a real nudge towards having tech all from one faction, and gently discouraging min-maxing the build using a Frankenstein of gear sourced from the far-flung-corners of the galaxy. At least that was my recollection.

Well, if it was that way, it certainly isn't any longer. They keep adding new alien races, storylines, and sectors of the galaxy, and some of my best ships were franken monsters with tech from a half dozen races. There is a core storyline that is primarily human, but if you play to the end of that will suddenly discover that there is significantly more around you that becomes reachable with some interesting new technology (trying not to spoil anything)

They have done a good job balancing the numbers so that everything requires some tradeoffs. More species/tech gives more choices and interesting variability. Some species make very efficient drives, others inefficient, more powerful but produce tons of excess heat, those folks also produce good passive cooling, others great active cooling but power hungry, etc. The ship hulls tend to match the sizes of the drives and weapon hardpoints of that race, but often work much better when outfitted with different kit (perhaps with some wasted space)

Plus the fleet management is pretty good. You fly your flagship, but you can park ships and switch your flag to different ships. So I might fly a fast little scoutship, then switch to an armor-clad behemoth surrounded my 20 of my heavy-hitting henchmen for some different missions.
