The problem with this is that a Diplomatic victory simply becomes an Economic victory again, as it was in Civ 5 (if I remember correctly). I almost feel like the franchise has hurt itself with this move towards different victory types. Don't get me wrong, I was in favour of it years ago, but now I have changed my mind.
This might be an unpopular opinion but there should only be one Victory type; Score. Scoring stops when a Civ achieves Domination or the Space Race. What madness is this that I speak of, you may ask? Let me explain.
I don't mean Domination in a pure military sense, but a blend of all approaches. Civs can still have their strong suite (military, culture, religion, science) on which they would focus, but victory can only be achieved by subjugating all other Civs through a combination of military, cultural, religious or economic control. Economic control could be a great opportunity to make Corporations a feature again.
Thoughts?
It doesn't have to just be economic. AI should only be open to the bribe if they like you for fulfilling certain things (agenda or otherwise, power quota or otherwise), or they could commission you to perform a task to get the vote (ala the mini quests in Civ IV). There are many ways to go about ensuring the bribe isn't purely about throwing money at a problem (which arguably the aid emergency in-game currently is).
