Sorry Julia, there's no new chapter here :D
Anyway, I remembered a situation from my first game tonight which really didn't make much sense and came out of nowhere. I retconned certain aspects of the world in the third game, not really thinking about how it would affect this specific situation as I had mostly forgotten about it, but strangely enough it makes total sense now.
Don't be afraid of retconning your story
Many people would assume that retcons are inherently bad and that an author should plan his story from start to finish to avoid using them, but it really depends on how the retcon fits into the overall picture. In my example it adds another layer to it without directly contradiction the events of the game. That's not to say that there aren't issues with it but that's to be expected for something that I made up as went along. I'm still surprised how well it all fit together in the end.
So let me use another example: Metal Gear Solid, one of my favorite game franchises.
The antagonist in the first games is Big Boss, leader of Outer Heaven and Zanzibar Land, and he threatens the world with his nuclear equipped Metal Gears. So he's evil, right? Just look at him!
Of course there are also bad retcons of varying degrees. One of the worst ones would be to bring a character back from the dead even though he quite obviously died. You need to come up with a really good explanation to turn this into a good retcon.
Let me use Metal Gear Solid 1 to demonstrate a bad one:
In this game Solid Snake claims that Big Boss told him that he was his father during their final encounter in Zanzibar Land, but I've played Metal Gear 2 and he says no such thing, nor does he ever imply anything like that. It's not too bad of a retcon but still contradicts established events and this wouldn't be the last time Hideo Kojima changed the series' history. I still like it though and look forward to the next game, which might finally show us the moment Big Boss "turns evil".
Don't be afraid to retcon your story, but make sure to add another layer to it instead of directly contradiction prior events. Of course you can have a few bad retcons here and there but be wary not to turn your story into a total mess that makes absolutely no sense!
