While I waste more time waiting for the DESIGN to "crystalize" (pun intended!) I find that I am developing the game further such that some aspects of the game are no longer "remote" or "esoteric" areas of the design.
One of those "areas" was the Ex-P Crystals. There had been an issue about these specific Crystals because they can be used with Actions to make some POWERFUL decisions impacting your turn a bit.
