I figured it was Rome, but also figured it was jokingly in "The eternal mists" (location setting of jack of all trades a slave trainer game in what is conceptually eternal rome stuck in limbo)
You have come a pretty long way from the original posts in this thread so Kudos to you. Story is always both the easiest and hardest thing to do. Since you can be like "My story is like the matrix but in a dream world concept" which sounds cool but getting from "Name your MC" to explaining why those cranes (the bird) just turned into origami cranes and what significance that will have to the player is pretty daunting.
My take on the easiest way is to break it down into pieces that are easiest to complete or make sense. An example would be first meetings. Assuming you know when each character will meet and you know who knows who. Then a lot of the talk is general nice to meet you, get to know you stuff. Knock all of those out of the park.
Another example would be sex scene. Whether virgin or not, you write the first scene of whatever type as an entry point for the all the future. So let's imagine you are doing the 7th sex scene. That can be easily knocked out because it will be a lot of general talk/dirty talk.
Other stuff would be the description of places.
Then finally move onto the actual hard story stuff.
Anyways it looks good so far.
Below is just my general recommendation for 2d artists who want to get better.
--------
Recommendations for materials of people who want to draw 2d better.
Andrew Loomis: His books are considered pretty cornerstone for an artist's education primarily "Fun with a pencil" for a beginner "Successful Drawing" and "Figure Drawing for All it's Worth" for intermediate, and "Creative Illustration" for Advanced. Other books can be woven in, but make sure the ones you take on are in your correct knowledge bracket.
Burne Hogarth: He was a master of Dynamic poses and his books on them really help to illustrate movement and action.
Bert Dodson: Keys to Drawing
