Since I bought Fallout: New Vegas, the game has crashed, froze, and the quests have glitched out and most still cannot be completed.
I don't see how this is relevant, Fallout New Vegas is still one of the best games ever made and a huge improvement over Fallout 3 in every area(perks, faction system, quests, map, region structure, skill allocation, progression, companions etc.etc.), nothing like it even exists...
Obsidian did a fantastic job, if you can't see that
Fallout New Vegas is one of the best games ever made you really need to do intense training or buy implant for your intelligence attribute...
