I've been very frustrated playing FONV on the Xbox 360. I've never experienced a more buggy game in my life. I stopped playing it waiting for the latest patch (the one that came out in December) and it still svcks. After updating to the latest patch I couldn't complete "Beyond the Beef" following the path I wanted. I can't finish "I put a spell on you" because Boyd is locked in the interrogation room and now I can't complete "Return to Sender" because the chief never broadcasts his final message. (The door closes and nothing happens.)
I was a huge fan of FO3 and looked forward to FONV, but I'm done with this game. I'll also won't be purchasing any other Bethesda/Obsidian games. Thanks for wasting my money and more importantly, my time. Great job on damaging the reputation of a popular franchise.
P.S. - I tried the LB/RB/X while booting the game up and clearing the Xbox 360 system cache via the dashboard and neither of those methods helped at all. I'm very disappointed in this game! Now, I'm off to write a bad review on Amazon and any other sites I can find.
