No obligation....?? Your kidding right? This texture pack should have been in the [censored] box with my [censored] statue.
You get what you pay for, if you don't think it is worth the price than dont buy it. If you didn't think it was worth the price, than you especially shouldn't have gotten the Collector's Edition. I'm a huge TES fan myself, but even I couldn't justify the CE price... and I even own the Collector's Edition of Mass Effect 2, a game I enjoyed much less.
I think Bethesda will continue to support the PC community where need be. They even gave PC the tools needed for modding, compared to most devs they are great to their buyers.
The Skyrim community has only just started, I'm sure you will be getting lots of free content, official and unofficial. Where as us poor console gamers can't even change our character's face halfway through the game. I'm stuck with an Orc who looks like he is still in the Legion while he is supposed to be a barbarian. That his face has low textures is of less concern to me.
