Gameplay is crap, enemy mobs around every corner. Bethsoft thinks you have ADHD and need attention every 20 seconds or you might get bored and quit. Worldmap is typical Bethsoft theme park with a new attraction around every corner. Story is complete garbage, actually all dialog is garbage. Three Dawg can shut the hell up. Consistency of the gameworld doesn't exist - what do people eat? Why are there raiders and dead bodies everywhere? Why do we need Super Mutants on the east coast? Why did we need to rehash the Enclave that was wiped out in Fo2? Why bring back the BoS again and make them shining knights? Why bring Harold to the other side of the continent just to turn him into a tree? This is ****ing bull****. Also lots of bugs - last time I tried it for lolz, I've played for 30 minutes. Then I've reached Megaton and the game kept crashing, so I just gave up.
Man, I can keep going forever, but it has been talked to death for years now and I'm just tired. So my tl;dr is ... it's a bad game.
