I've been playing the game patched with 1.01 for about 20 hours now, and it still locks up a lot. Sometimes during loading screens, but also in the middle of the Mojave Wasteland. XMB is always unavailable when this game locks up, and you have to press the Power button on the PS3.

The game is great when it works. But people will eventually stop buying your games if you at least not fix them when they are out in the wild. You should have run larger closed beta tests to avoid so many bugs. In any game so complex and large, there will be a lot of bugs to squash. You won't be able to find them unless you let many different players outside the company beta test the game for some months before it goes gold. Today where it is so easy to distribute data across the internet, there is no excuse for not doing this.
