..but every planet has the same resources
Who is telling you guys this garbage? This is the third time I've heard somebody say this despite being completely incorrect. The only resources that appear on every planet is plutonium, iron, heridium and carbon.
it would be cool if it were a risk to special resources that only appear rarely, but what's the point in fighting some super robot just to get the same resource i can get on every other planet
the only reason to do that is specifically to fight the super robot
Gravintino balls, vortex cubes, sac venom and albumen pearls are endangered or "protected" resources that are pretty loving rare. Gravintino balls are the most common, then albumen pearls. You find them everywhere (in the galaxy, CERTAINLY not on every planet). I've been on about 4 planets that had sac venom, and one planet with vortex cubes.
