Going beyond three or so colonies effectively requires AI cores which have the penalty of hegemony inspections and possible future remnant activity.
For me, the worst part is Pather cells that cannot be dissolved (because cores become sticky soon enough), which will be fixed (no more ignoring terrorist attacks), although they only appear at size 4 or bigger worlds, which means keep those worlds at size 3 to prevent cell formation. On the other hand, size 3 might make them vulnerable to the zombie pirates... unless player befriends them.
Although bribing Hegemony will require story points, so... sat bomb them all away to eliminate that nuisance.
Not complete 4X, just parts of it.
Yes, I would not want full 4x. They are annoying to play.
It is like calling Starsector a full-blown RPG. It has gold (credits), XP, levels, and encouragement of murderhobo behavior, but none of the tedious turn-based and menu navigation just to kill some slimes or "What do you do" off-the-rails hijinks. At least Starsector lets player develop from murderhobo to space lord like early TSR-era D&D fighters.
