Here's a sci-fi action RPG where your inventory is a ship designer and your skills are a tech tree
An indie action RPG has a cool twist on the genre, having your character as a starship with parts and a crew to be upgraded rather than the normal single warrior and their inventory of random stuff. Starcom: Unknown Space looks like just that, a more low-key but still very enjoyable action take on the space sandbox genre that also blends in narrative events as you land on and explore new planets.
