loading times are freakishly long, which is worsened by the fact that the overwhelming majority of buildings are separately loaded areas. i understand there are mods to fix this, but given how poor it is for this mod it should have came pre-installed with the other utility mods settlements are nonexistant and workbenches are extremely sparse and only accessible mid-late game, which means you have nowhere to organise your items and crafting for a good while into the game. the world also feels very empty compared to fallout 4, as very few buildings have any interior and those that do are often completely or almost completely empty (no loot, furniture, npcs etc) unless they are part of a quest. there are also a moderate amount of bugs, but these are typically not game-breaking, and understandable for a project of this scale overall a very good experience but doesn't feel like a proper "fallout" game in most senses; the post-apocalypse vibe feels lazily conveyed and inconsistent, and while the roleplaying ability and elements are similar to new vegas, these are limited by the sparseness and limited depth of interactable npcs and the slowness of gameplay due to absurd load times (around 5 minutes for most loading, regardless of area size) and the segregation of the map into many, many sub-areas (like far harbor and nuka-world in 4, but less than a 10th of the size) constantly making you endure more area loading
