CYBERLOUS'S PROFILE

I'm not sure if this goes here, but what the hey!
So I was thinking, and I realized that I want to sell my game commercially(if possible), not entirely for the money, but so no one else can claim it. But I want to know how old I have to be to do so.

Okay so at the beginning of my game the protagonist decides to escape and I'm curious how long it should be until she escapes because the beginning.I'm thinking short, but I could be wrong.
Maybe I can use the escape scene as a tutorial, and then have the protagonist wake up outside?

Okay so I have an idea for a game I'm making that I plan to be completely open world and free.This idea is to not have a main story that the player has one choice of going through, but multiple different stories that are optional and can be triggered by doing certain things.Now I come to the difficult part, I want to let the player have the option of exiting the story whenever they want, however, I have to decide if they have to start all over when exiting a story or if they can be taken back to where they were before if they choose to.

I feel like most people think we're country...

I need help.When I tried to add NPCs(the city is large and so I want there to be NPCs that are going places) all of them moved at the same pace.Also, how would I make cars and stuff move around the map?
