Wait, bugless games get released these days? Seriously?
Oh come on, I agree that there was a pro-Bethesda bias in Fallout 3's reviews (just compare the comments on the forums on release with the reviews) but that does in no way excuses releasing an unpolished game. And just compare the general polish in Bioware releases (with the rather noticeable exception of Awakening which had its score dragged down in reviews for exactly that reason) to an Obsidian release.
Pro-big developers bias does in no way excuses small developers to publish buggy games that lock up constantly on consoles, and unfortunately, that's a pretty common complaint.
