Do units that are destroyed or discarded count for final scoring?
Do advanced actions that are thrown away count for final scoring?
Do keeps that I capture and then someone else takes away count (for me) for final scoring?
Do crystals that I used during the game count for final scoring?
No. None of the stuff that you don't have any more, scores for you.
I can just imagine what my opponents would say if I made a little pile of stuff I had used up during the game and tried to score for it at the end!
