Hello! If you ever played in Harthstone or Gwenth, you know that some game mecanics bound with leader of your card deck. Leadrs in these games have interesting spells that have a gret influece on your strategy. It will be cool, if leaders of factions can affect on gamaeplay within the confines of chosen faction. And we will have interecting quests to change ower leader, to change main vector of development of ower nation.

For example: United Empire(start leader: Emperor Zelavas) can increase rebillion power in discovered enemy system (with CD in 10 turns). You dont like this ability, and start your copany to change him. You'll get quest: "Secret conspiracy". When you done it, your change leader on? may be, on hes dougter (with her unique) ability. And type of goverment will stay on 'Federation'.

Every factions will have their owen list of leaders  that have different advdntages in its unique playstyle. These example is thery simple, but i think you anderstand me.

Ps that mechanic will be grate with system of espionage in the feture.
Pps my english is not so good, so i am sorry.
