How about if you deliver a buggy shit that plays like shit and is not fun to play because of all the crap they put in? That IS a good reason to not pay the full price. It's a simple economics rule. A customer gives you the money if the return is of high enough value to justify exchanging money for it. These are professionals. If they want my money they have to give also quality and not hype-crap mixed with more bad design choices and bugs than one can possibly sustain. If I pay I expect quality. Here this is not the case. And no, I give a rats ass on hyper-super-duper-fucking-graphics-shit if the story and game mechanics stick out of their ass and you see huge holes where they ripped good stuff (from early games) out and glued in a non-fitting piece of frickle-ware <.=.<
I just want to say as well, from a QA standpoint I completely agree with this. What Bethesda has and continues to put out does not justify the prices they are charging. The consumer deserves better than this, there are far too many bugs in all their games, support is usually abandoned pretty quickly in favor of DLC creation. Given how big and bloated their budgets have become, why hasn't their QA team expanded and why hasn't the quality of the product (stability wise) improved? Dragon is right, we have to have standards, if we go out and buy games when they first come out and their buggy as fuck, we're just encouraging them to keep doing it, this is how publishers think, that if the game sells heaps during the initial release, then everything is fine and nothing has to be changed or fixed. I've encountered that thinking before in my work, its a bad way at looking at your product and it really treats the consumer with no respect at all because you just assume they'll buy it again at release every time.
If you made the kinds of money that Zenimax makes, you'd be reinvesting into your products to make it better, not suing Indies just because their game has a word that is in your game's title. We've seen no improvement stability wise at all, and this is always the thing that many criticise Bethesda for, but rabbid idiot fanbois dismiss as being "Character" or "in-jokes" or "Charm" eg. Gamespot's review of Skyrim he just dismisses the bugs as "Fine" because previous games had them as well, that's a shit outlook the customer paid for quality, these are major issues and they need to be fixed.
When you've worked on a game, your thinking on bugs does change significantly, it annoys you a hell of a lot more than it should. Its both a gift and a curse, a gift because it means you make better games, but a curse because you can't enjoy the things other people do because you see it much differently.
