- Of course, as the title said, how saturated is the market here?  Is there "fantasy fatigue" or are people not as interested in a gritty adventure?

Theres a lot of people here, I don't think anyone has a clear cut breakdown of demographics as far as genre preferences go. You just gotta put your interest check out and see if people like the game. 

- Would anybody enjoy a combination of free-form and dice in their story-driven adventure?

Yes, so much I would. I've tried to do it a couple times, but have never really had anyone bite. There is a tabletop section, if you haven't looked there, but it's mostly specific systems like DnD a d pathfinder. I reckon you're looking for more of a hybrid. 

- Would you join a RP knowing there is a strong likelihood that you will end up going through a few characters due to deaths?

I've been waiting for an RP to kill one of my characters. 

- How much grounding, consistency and "realism" do you like in your fantasy settings?

I hate seeing people wielding six foot long swords, and boobplate armor and that kind of thing. 
I want magic to be consistent and reasonably well defined. 

- Could you bring yourself to play a (mostly) normal person in a land where magic exists?

Totally.

- Did you like Game of Thrones but think to yourself, "Gosh, I wish more people ended up dying".

N-no 

- Is Final Fantasy Tactics the best Final Fantasy?

Man I dunno, I've barely played any of them.
