It's a buggy game? I've played the thing 12 hours and haven't had any more bugs than I did playing the Game of the Year edition of Fallout 3.
The only glitch I came across was a bug I was fighting getting stuck in a rock. Twas nothing at all really.
What you may not be familiar with is that PCs are not like consoles. Since consoles all have the same hardware, it is significantly easier to troubleshoot it. And if a console player has an issue, it's easy to repeat on another console.
With PCs, due to our myriad of configurations (literally billions), and because the technology used doesn't necessarily support the same features, 1 PC user can have a significantly different experience than the other. Because PC hardware/software is not developed to standards, the end users suffer.
