I'm not puting 5 stars since i didnt' played much, but considering the bad notes due to the game crashes and loading time, I will give you a few advise in order to get a playbale game. As a non-user of mods usually it took me a lot of time yesterday, but I managed to get a good version and i would like to share the method with you. DISCLAIMER : This post does concern you if you bought the game on GOG and use a Window device, i'm not sure if it's similar if you bought it on STEAM and use any other devices. Firs of all, follow STEP BY STEP the advices given on this topic : https://www.gog.com/forum/fallout_london/fallout_london_quick_start_guide_common_bug_fixes Pay attention to not forgetting any step of the installation, and add Buffout 4 and it's preloader plugin as recommended. Run the game one time to check if it semms OK. Now you have the full game ready to play, I will highly reccomend you tu add another Mod, beaucse loading times makes the game really like a pain in the a**. Go to : https://www.nexusmods.com/fallout4/mods/73469?tab=files and manually download the second file (For the game version 1.10.163.0 and lower (London) ). DON'T PAY ATTENTION TO THE REQUIREMENTS ; THE GOG VERSION ALREADY INCLUDE THE REQUIRED FILES Then go to to your donloads, and copy or drag and drop the content of the zip file to the next folder : C:\Program Files (x86)\GOG Galaxy\Games\Fallout 4 GOTY. It should have fixed the loading issues ; i played a little hour after doing all this and didn't met any problem. Lets's enjoy guys ;)
