I just recently decided to actually play HD instead of just buying it because Space Rangers is my favourite series but gosh ... after 16 hours of streaming(30 years in-game) I just hate the changes in HD AWA.
While both Reboot and HD starts well, the added pirates just make things worse. By year 3304, Coallition had only 30% of the galaxy, Dominators had half of it and pirates had the rest 20%. Even though pirates dont seem to have a lot, it turns into pain late game(check images).
I played on 100% and started the game as usual, do missions, get rich, get gear and start fighting. Sadly at some point pirates and dominators captured the middle part of the galaxy map so I was locked in a place in which I can only travel between 5 systems so doing missions got even harder.
The worse part is that apart from Keller, the other 2 dominator's mothership doesnt seem to move AT ALL. So the only way to beat Blazer and Terron was to fight them in their solar system of choice or upload the programs. As far as I remember in Reboot all 3 motherships was often making black holes to capture system in "remote" places.
Anyway I manage to defeat all 3 dominators and surprise surprise... I had to liberate 3 systems that was still under their control( explain this ..) . Every system had ~ 15 ships and 1 flagship ... from them only 3-5 ships was with old tech.. everything else was 30-35% shield and 5-9 hull armor so unless you get a military squad and your own ranger squad you stand little to no chance to free it.
When comes to pirates.. well...

Frankly I just quited the game after I got the 3 motherships since the game turned into mindless grind.
