Anyone but me find it far too predictable and silly that every planetary system has a predictably number and type of resource asteroids?
it would be better if sometimes that Ice planet only had 2 crystal, or sometimes it had 4... or perhaps sometimes a lava planet had crystal... or asteroids having less or more resource asteroids of varying types.
Also I could see having 'mega' resource asteroids, that simply have more crystal than others, or won't run out for some time, or that you could build 2 mining bases on... you could have green crystal for example...
Hell you could just make some crystal asteroids not be the same color.
You can still have pre-dispositions, such as ice planets being crystal heavy, but some variety would be nice...
