Really? I can't think of a single thing that was promised for Skyrim that isn't there. The Radiant AI thing in Oblivion was a blatant lie, but everything regarding Skyrim seems to have been sincere.
I believe there was some mention that the PC version would look better than the Xbox version. Also something about faces melting, lol. My face is still pretty solid and dry. The game looks good from far away. Or if I squint. And I have terrible eyes and a brand new PC with a $500 graphics card. Tbh, I feel like I'm playing a $2,500 xbox. And that thought does make me pretty mad.
I don't feel cheated, no, that is too harsh of a word. But I do feel like like they made some empty promises, and they did kinda screw over the PC player base by shipping such low res textures, shoddy shadow & lighting, and only optomizing it for consoles. This svcks pretty bad, especially when they promised us that people with high end systems would be able to crank up the details. I believed them, and spend alot of money based on those promises that I otherwise would not have. I really really hope they fix these broken promises in the next patch.
