When I was preparing for text 101 section after the second lesson, I started to make the story in a large scale 
. However, I will try briefly share my thoughts and ideas. I might change the order of the questions asked in the video a bit.
Core Game Design:
What is my theme?
Medieval, (and maybe Futuristic). I like the medieval and I don’t like to be missed up with overloaded futuristic touch. but here maybe I will add some from that touch.
How I would want the player experience be look like?
I would like to make the player feels mysterious and adventure.
Core Mechanic:
Story directions, Quest might be completed or not depending on player choices.
Core Game Loop:
same as what @Rick_Davidson said in the course video.
“Player is shown text on what is happening in the world of the game and given 1 to 3 choices on how to progress.”
Story Hooks:
Who is the Player?
The Player might take be taking multiple turns depending on the situation. as far as now I am planning to let the player be as two characters, which are King’s heir and king’s personal guard. and I might add more in the future and post again.
Story Settings:
a castle in siege (classical right 
). but the details are important.
What is the threat:
Neighbour empire
What is the goal?
Survive and Rule strategically
and that what I have thought of, so, what do you think?
Note: I will reveal The story after completing the section.
