Nah, it doesn't depend on luck the only reason why more people have problems with bugs, crashes and whatnot on a pc is the vast variety of hardware + combinations + configurations out there. Fallout 1 always worked fine for me, had more problems with Fallout 2 until I bought a new computer (not for FO2 in particular, just needed a new pc eventually) and it worked great then. Same as FONV: I had a bit of trouble with DirectX 11's backwards compatibility in relation to DirectX 9.0c plus FONV isn't too fond of NVIDIA cards/drivers either. Don't worry I found a solution, eventually.
However I'd never purchase a future Fallout series for my console ever again. Too many regrets!
Consoles aren't consoles anymore imo, by that I mean: go to store -> buy game -> go home -> put game in console -> turn it on -> play -> period!
Too much connecting to the internet for patching, added content, tweaking and stuff like that. Well, I can perform exactly the same tasks on a pc only better!
