I've played 80 hours and still have a lot to do. And the game has only frozen like 2 or 3 times. And one of them wasn't random. It was because I went into the Mojave Outpost bar and started shooting grenades with a grenade rifle. Imagine all these bottles and shit jumping around. Game slowed down and crashed on like the 5th nade.
Also, I am proud to say THAT I KILLED THE GODDAMN LEGENDARY DEATHCLAW IN VERY HARD (WITH HARDCORE MODE ON TOO)!!
With melee too! Ranger Takedown and then stomped in VATS 'til it died, hahahahaha! Its fucking head EXPLODED! Made me so damn happy! (I love the ballistic fist, best god damn weapon ever)
I am lv30 and the thing could kill me in one goddamn hit, hahaha,
I also like how the super mutants aren't retarded now, unlike in FO3. I don't like that the game references FO1 and FO2 so much but pretty sort of ignores FO3, tho. Kinda lame. Bet that the people that have actually played FO1 and FO2 orgasm over it.
I think it's a much better game than FO3. I love this freaky thing.
