Hello. 
I'm new to this format. I'm really itching to do some dark souls inspired stuff, but I'm not really sure how to run something plot-driven. Possibly with some light TTRPG elements. Does anyone have any advice or tips for me on how to run my own game?

I will add to what Tokyo had said. 

Want RP but soulslike? Then... high five! You would like to be a simulationist GM, where actions have consequences, and the world is a living, breathing thing. 

But it is risky, and you need to communicate this aspect of your RP clearly. Heck, I am this kind of GM; I mentioned my rules, yet people still miss the memo. People in casual RP want quick protagonism. 

Plot-driven? Then Linearity is your friend. Not saying it can't be done in sandbox, but I feel most would find plot driven and sandbox counterintuitive.
