AI is terrible, you can kill the first Deathclaw by simply walking through a small gap near the car and he keeps circling until you destroy him with the minigun. Other enemies stand there whilst you keep shooting them or walk past. I preferred to adventure alone as Dogmeat screwed my stealth up and got in the way. Sentry guns are easily dispatched by shooting round a corner where the turret can't hit you.
When you die the ragdoll models are the worst in any game ever. Should be cinematic but embarrasing.
The first faction use pea shooters but are happy to give your character power armour and a minigun, something you got at the end of FO3, within the first 30 minutes of the game.
Average graphics, some objects cant be moved for physics limitations.
Dogmeat can't die, one of the best parts of fo3 was when you made a mistake and he got took out, you were made responsible for wrong actions.
