Paradox's historical grand strategies are too complex for my feeble mind so if they make one dumbed down with less mechanics to be compatible with more time periods that would be fine for me.
Im a big fan of the purge the galaxy of xeno scum so my cute aliens can convert everyone to food as was ordained by dear leader. Long live the empire, least till the late game crisis unless you become the crisis.
Also planet crackers, the right way to create a neutral zone and mineral source.
Oh I'm sorry I didn't realize Voice to Text had screwed up my comment, I meant to say that a lot of the games already have that mechanic. At least CK2 to EU4 did. I think eu4 had one that branched to Victoria 2 as well, though I'm not sure.
