I got hyped by the TV series so I will play the game for the first time (yes, I know, it took this long). I usually prefer to buy GOG version of a game but I saw the rating of FO4 GOG at 3.9/5. Why is that? I have read somewhere that there is technical issue of some sort which includes modding for GOG version? I expected higher gamer rating for FO4 in GOG but a lower rating typically indicates for me some genuine issues.
Edit: also the GOG Version says it does not include the Creation Club. What is it and is it in some way better than using Nexus mods?
The Creation Club is Bethesda's paid mod system. Just use Nexus Mods because it's free.
Fallout 4 is a FPS with some very light RPG elements. The other games in the series are RPGs (outside 3 and 76). Also it's story is badly written. It's why the game is poorly rated on GOG.
