Tom Chick writes: "Fallout New Vegas simply doesn't work. I'd estimate my Xbox 360 locked up maybe once every two hours. The problems started to progress from occasional freezes to recurring freezes in the same place. My last ten hours with New Vegas have been spent troubleshooting, or going back to replay from earlier saves in the hopes that I can somehow work around a crash. But my last problem has effectively brought the game to a screeching, inglorious halt."
