One question, do you already have the story finished or are you making it up as you go along From the game and what year do you think you'll finish the game?
That's two questions, but I'll answer :D
The whole game is not written. For context, we just finished episode 6, and the game's total word count is currently 144,394. For context, that's longer than Return of the King. So it's going to take me a while to write all the episodes I have planned —24 in total. So while it's not written, a lot of it is planned, so I roughly know where we're going with an end goal in mind.
As for what year do I think the game will be finished? I don't want to give an exact year, because then that will become the thing people expect to happen lol. But it will take years to finish. It's a huge game with lots to do.
