[God Emperor]

I've personally hardly ever use mines or satellites (although I dont usually play above low bonus - played medium a few times).

I rely on WP's equipped with point defence and large/massive mount weapons backed by ships. I try to avoid spending on defensive weapons and buy ships, ships and more ships.
Might change my strategy a bit once the AI can use cloaked ships properly.

I dont use fighters or missiles much because my mod incorporates heavy point defence on the AI ships, which means I have to have a lot to make it worth while.
As a note though, I play tactical combat...
