Story is not that bad, but story telling is very poor. The world is beautiful. Everything is designed very well, but ther is not a lot of variations of enemies, items, equipment, etc. Developers missed a huge opportunity on this game, game is two step far from a very nice game, and they didn't took that two step.

Main bugs and how to fix:

1- one of vaults has infinite loading screen, for fix you should restart your pc.

2- one of vaults has a low frame rateand high GPU temps and you can't do anything about it, even lowering graphics wouldn't work. You should just be patient and do that part.
