I bought this game, thinking it would be terrible but...
Firstly the most controversial and complained about part of the game. The visuals. Yes it's been said that the ps3 has the worst of the visuals out of any port of this game. But seriously; if no one had said that, I doubt you'd really notice it. The game is beautiful the landscapes; the colors, the little particles of brain and blood splattering across your screen. It's awesome.
The story seems a little iffy though, as you're chasing your father around, but you fix a radio tower, and everyone's pip boy has a radio tuner, meaning if you sat at the station and broad casted for your dad, he'd eventually hear it...so....uh? Other than that, the massive amounts of quests and ground to cover makes the game really nice.
Physics aren't tip top, but they're pretty good for an RPG. Rag doll corpses is always a plus in my book; even if the game is terrible, rag dolls make me drool! And rag dolls in the VATS system, lord you can't go wrong. Though you can make some lethal and cheap combinations with the VATs system.(try frag grenades).
I've played the game for over 8 hours already, and there's still so much to do; so I'm only looking forward to more.
