the last (ok, well, the second..) game I finished involved heavy raids on datacenters, a use of the super-processor (it spawned RIGHT next to my homeworld!) and destrying all the co-processors.
It ended around maybe 400, including the second AI core station, but I kept it barely under mk2 raids as much as possible..
Then again, I like playing a fast paced game, so it was set to 1 aip per 15 minutes, AI's were assassin and mad bomber.. so that helped keep their defenses light.
I much rather this way, the whole turtle thing doesnt really work well for me, and special forces guys are hard! >.>
