No crashes for me, just lots of save game corruption. About half-way through Honest Hearts, not really enjoying it, I may restart as the story hasn't grabbed me and I forget what I'm meant to be doing. Dead Money was a lot richer, darker and interesting. This feels like a big piece of tacked on poop, starting with Joshua Graham's miraculous change from a killer to a less evil killer and monsters ported from FO3 or simply bigger/slightly changed from standard New Vegas (like green geckos, just regular geckos that spit spore plant poison). Only the recipes are useful, the perks certainly aren't.
