In the meantime you can use this. Feel free to ask if you need further help.
Edit: I found this guide. Hope it helps!
(You can also downgrade manually, instructions at the bottom of the page. https://fallout4london.com/release/ There's also instructions on how to manually install the mod if you are having issues with the GOG Installer, there's ways to extract the raw files from GOG installer executables)
Thanks for the game! Now, I started Fallout 3 not long ago, is there any commonality to the story between the Fallout games? Are they following each other? Are they alternatives of the same story? Is it something else?
To answer your original question about the timeline, this may help.
A detailled version is here (not spoiler free!).
You can probably play the games in any order, but beware the first two are rather classics today, within the technical limitations of their time.
There's also the Tales of two Wastelands mod, which combines FO3 and New Vegas on the latter's engine. I've installed that, but admittedly was too lazy for a complete playthrough.
FOLON is a total conversion, with some references to the other Fallouts, bacause it is set in the UK.
@TheHobbyist @Cobrachicken I have not heard that term in a long while, but I'm also old and have been out of the game for a while. A total conversion is technically a mod of a game but replaces all (or at least close to all) assets and game logic (to the extent it can be modded), effectively using the game as a game engine to make a new game.
Exactly, thank you for this explanation. It's in one of these videos that they explain the new assets (2d/3d models, textures) scripts and pathfinding stuff they created https://fallout4london.com/world-of-fallout-london/
Sry on mobile else would link to the exact source. Very impressive feat.
UPDATE:
Santiago Santiago has updated a video on how to install Fallout: London on Steam Deck.
