For me it seems most people overreact, i've had barley any bugs and none of them made the game unplayable. Im on pc though. And even if your game crashes every 45 min in my opinion it will still be worth it since it's such a great game :>
No overreaction here, I seem to find game-breaking bugs every time I play.
Last night I was in the middle of For Auld Lang Syne and decided to pick up the last two companions while I was in the area. So I sent Arcade back to the Lucky 38. Oh, what's that, I forgot the NCR went permanently hostile when I had to kill Snuffy for randomly going hostile. So now I have to permanently wear NCR faction armor so they won't always attack me. Oh yea, rangers and NCR NPCs are still hostile and will attack on site no matter what my reputation is.
So Cass can't join, achievement ruined.
No biggie, I'll go pick up Arcade and finish the quest...oh no, can't do that, he's permanently stuck at the Lucky 38 and thinks I have a companion with me whether I do or don't.
I have about a dozen incidents like this, I almost lost my companions permanently yesterday, but thankfully as I was readying the wiki on the new vegas medical clinic I learned that if you get the regeneration surgery and leave with 2 companions still following you THEY DISAPPEAR FOREVER. Which is amazing, because I saved it for last and was about to do it.
My first play through...no bugs. But it was a short 22 hour quickie. But with two other characters, where I've learned more about the game and done more outside of the main quest, I've hit hundreds of game breaking bugs, sometimes many at once. These two characters alone only had about 90hours of gametime.
