I read what you have so far and I like it! I like that it features Ethan, Lyra, and Kris. I also like that there's not much focus on battles, since that's pretty much the bread and butter of the games and anime. I look forward to the updates!
I think I can rest easy now. It looks like the main reason there were so many USUM shills before is because of Game Freak's lies regarding how different the games were going to be. After the datamine, I'm seeing a different side to people.
I saw the executions and most notable scenes, but read the scripts first. (Since that's what was leaked first.) To be honest, the fake spoilers going around made for a much more entertaining story than the real thing. But the meta twist makes for good fanfic ideas.
I followed the Something Awful Let's Plays, then moved on to other Let's Pays and summaries. I'm all caught up on spoilers for DRV3, and I've seen all the anime. Did you like the anime, btw?
I'm not too big on the Telltale TWD series, but looking up S;G 0, I'm really loving the aesthetics. If I can't get this game, I'll at least try and follow playthroughs or something. It looks really good.
Regarding on your fanfic, although I appreciate your notification, but I guess such kind of traditional game-verse journey fic is just not my cup of tea. Although the beginning so far is not bad, but I would suggest to have a bit more originality especially expand the worldbuilding beyond just what the game had already provided.
