It's between Witcher and Batman for GotY for me but I haven't finished Fallout and I'm enjoying it a lot. I actually thought it was cool that things like the radio stations having some of the same music from previous games are in this since it takes place at the same time as the older games.
I'm enjoying FO4, not tryna knock it too much
The gunplay is not only much improved, but actually legitimately fun this time
But it just left me kind of cold in some way, not feeling that endless pull to get back to it, the way I felt with FO3 and especially Skyrim
I think this feeling is at least partly because of the crafting/scrapping system
I think the crafting system is excellent, unfortunately, its directly tied to the scrapping/scavenging system which is a major chore and a time-sink
I dont blame Bethesda for trying this out tho, because they've always had crazy amounts of scrap and now they've tied it in to something thats actually useful,
but it ended up making the feeling of exploration and adventuring much more tedious for me because you're constantly sidetracked by managing scrap instead of finding exceptional weapons/armor loot
