What is your favorite SE4 feature?

[AJC]

I like SE4 because of the ability to change the game and its a interesting strategy game against human opponents.

combat: Since the limitation of "only one ship can occupy a square in combat" was done by demand in the early development of the game- I would like to see an option added to the set up that allows multiple ships to stack in the same square in combat.

I would like to see a defense added for every type of weapon damage in the abilities file.

I would like to see ground combat maybe similar in format to Star general.
