Yes, I said it and mean it.
It has ‘NPCs’ that feel way more alive than anything bethesda ever put out and even an anarchist faction that so far acts like actual anarchists do/would in real life not the common idea of anarchists in most media.
Apart from the ocassional crashes (even with the patch), this is a great game/mod and I highly recommend trying it out if you have Fallout 4.
Edit: You can get it here
Instructions on how to install on Steam are here
Instructions on how to install on linux are here (though you can skip installing Buffout as the latest patch has it already). I do recommend installing it through Heroic if you have a gog account though, makes it a lot easier than Lutris ime.
Make sure you turn off weapon debris, you can do this by finding Fallout4Prefs.ini for both Fallout 4 and Fallout London (just in case) and setting the following options thusly:
[NVFlex] bNVFlexEnable=0 iQuality=0 bNVFlexInstanceDebris=0 bNVFlexDrawDebris=0
I think he would be pretty happy, since it would mean more sales of Fallout 4 when all the new people show up to play London. Like how Bohemia Interactive leaned into DayZ because it was causing a huge uptick in sales of ARMA 2 before they made it standalone.
