I kinda hope you have to become king/emporer to unite the lands for the arch demon wait a sec I mean the dragon god thing lol I love how it was handled in x-pack for elder scrolls 4 were you become the madgod you would go out and do dutys to lands i liked that alot i hope once you become king/emporer it opens ton more side quest i love side quest in elder scrolls games i do agree with you on one thing i never liked the followers you got elder scrolls 4 they were pretty useless but at that point you so uber you can take out a battalion by you self you won't need them lol
Being king/emperor is a whole different type opf gameplay. Firstly you have practically infinite resources so you have all the money and items you need and there's no point in looting. Secondly, a kings main duties would be mundane stuff like public appearances and things which bare no resemblance to TES gameplay like organising squadrons in war. It would also change your interactions with NPCs dramatically and I doubt they'd ever arrest you for anything other than serial murdering. You could go into a shop and take their legendary item and there's nothing they can do about it because you're the king. And then they'd have to implement a massively complex dynamic politics system and we'd end up with an RTS instead of an Elder Scrolls game.
I don't know perhaps its time for change and it looks like you the PC has been rised by estabon one of the last blade's so you might have been groomed to become a king
His name is Esbern and he did not raise you, he saves you from execution at the beginning of the game and tells you about how you're the dragonborn and have to defeat Alduin, and nor is there any reason for him to raise you as a king if he had raised you. You are NOT the rightful heir to any throne.
