I'm talking about the star system map, not the sector one. In Diablo/Din's Legacy, the map is generally more interesting and varied: different shapes determined by walls and such, different rooms. In Drox, having to sweep the whole round map every time for the gate to the next star system becomes painful, especially because you see multiple quests for the next system and have no idea how to get there (the gate is hidden). You want to meet the new aliens and explore other systems, but the way to get there is cut off purely by a searching problem, where the map you need to search through is empty space.
I would even be ok with being able to trade with local races for the locations of the gate and their planets.
