Buggy Games

So, what are the buggiest games you've encountered lately? Here are mine:

Fallout - New Vegas: I found quite a few bugs in this one, some of which were easy enough to fix through various means, although a few were game breaking. The one that stands out the most takes place in one of the games casinos. If you back out of a conversation near someone near the door, you could never enter the casino again after leaving, or it'd lock you into a dialogue loop.

The Walking Dead: I've been trying to play this although, for some reason, the game didn't want to carry my choices over from chapter two into chapter three. Once I got that figured out, the wonderful, moody music started randomly starting and stopping.

And my latest (and most frustrating as it took forever to download)...

XCOM - Enemy Unknown: Taking the top of the list, this game is so buggy I can't even finish the tutorial. My computer runs it beautifully on full specs... Until I'm instructed to build the alien containment, at which point it hard locks my computer and I have no choice but to reboot. Talk about frustrating. From what I gather on the forums, the company who made it doesn't seem to care about fixing bugs either.
