3. Better planetary militia: I mean I know they are not supposed to be able to stand up to troops but I really enjoy those planetary invasions where it becomes a real nail biter and I'm going "Can my troops pull it off" right up until the end.
I would also like to see planetary milita count as a certain percentage of the population.

A fraction of your population IS militia. Not anything like a whole 1% though... that would just be crazy. One "division" of professional armed, armored militia with good tactics per X million people, rather than just ten million sidearm-wielding couch potatos running out as cannon fodder...

For good militia in SE4, go into settings.txt
1) Set # ground combat turns to 1.
2) Set population per militia to 1.
3) Set militia hitpoints to 30+
4) Set militia attack power to 1-10, depending on how difficult you want it.

Now try taking planets
Still too easy? Try SJmod... against a bloodthirsty race who enjoys it when you land troops for them to butcher
