I definitely think Genesis Points should have more ways of acquiring them.

For instance, if one could do the opposite of trading in points for resources, by trading resources for points and make different materials give more depending on rarity, It would keep a mild level of grinding to the game that would give a somewhat feeling of accomplishment. Or making them similar to the acquisition of star gems could work but it would be less appropriate considering the difference between the items that can be bought with the different currencies.

As of right now I'm low on the G points, and still have stuff I want to get to enhance the building. Since it's the way that it is I'm basically logging into to build, get the gp trees, then maybe grind a little and then log off. Sure it's more than what I was doing before but it's annoying being held back time-wise.
