Yeah, there are a few people that feel that way. Most of the Steam reviews that mentioned that were much earlier on in our Early Access period though.
Here's the major things that have changed in Drox 2 compared to Drox 1:
Build a unique ship with a new skill/command system
Enjoy better graphics (normal maps, better specular maps, and higher resolution textures)
Deal with more treaty types (vassals, tributaries, protectorates, and federations)
Find more component types (plasma cannons, ramming components, probes, etc)
Experience faster movement and combat
Interact with randomly generated races (just the young races)
Discover way more interesting things while exploring
Protect or exploit primitive races
Find crew with skills
Place spies on planets for better info and spying activities
Access much more information on the 4X aspects
Play as the rebels of each of the races (42 total playable races, rebels, and subraces)
Win sectors with the new Guild Win
Play with better controller support
