However I've been always let down.
So, you've always stuck your hand back on a hot stove after its been burned eh?
I see your point with other game companies having fewer glitches with their products.
And no, I won't come at you saying that Skyrim is bigger therefore it would have more glitches.
Its the fact that this type of game is strictly non-linear, making the end user (You) available to do whatever.
Ubisoft, which makes mostly linear games, Splinter cell, Ghost recon, Rainbow Six, ect. Pretty much follow this path, we give you little room to manuver, but you'll end up killing this
guy at the end of the beaten trail. Easy to catch any repeatable bug.
As for Rockstar, they do make sandbox games. As for GTA, most items you see, buildings, houses, ect, are mostly just props. About only 6-8% of all the buildings you see you can really enter. Which would leave less interior programming to be done and focus on the outside.
Same probably said for Red Dead redemption and LA Noire. (I personally never played LA Noire that much) In short, they don't have 50+ random dungeons and numerous meticulously detailed accessible houses/shops/inns you can stumble upon, plus the vast open outside world to explore with scalable mountain tops.
And from the shear scale of Skyrim, IE Fallout 3 had around 39 quests, Skyrim has around 250+, you can say that there is a lot more content and instances to program through and test.
As my last statement though from my previous post, in my experience this has been one of the lesser bug filled game that Bethesda has produced, given the numerous contents of the game.
So, in short I am sorry that you are experiencing more technical issues that I have been, and I am sure Bethesda is well aware and trying to take care of these problems as fast as possible.
