I can relate to the OP, but for me it was with Arena. Granted, it was a lot easier to stay away from the heaps of info back in 1994 because there wasn't any... lol. There was barely an internet! So I went into Arena completely blind and ignorant to everything. Same deal with Daggerfall, for the most part. With information so easy to come by for Morrowind and Oblivion, I read every review, watched every trailer, every "making of," every sneak peak. I stayed away from spoilers, though. I can't really say that it ruined anything with having some prior knowledge of what to expect about certain things. But at the same time, I could see the attractiveness of ignorance. I still remember that feeling from Arena. However, even though I know nothing about Skyrim (yet), I still am very familiar with the Elder Scrolls series, so I already kind of know what to expect in some way regardless. I know about the land, the races of people, about guilds, about quests, RPG elements, ES lore, etc. So although I'm ignorant to specifics, it's not all foreign to me anymore. I think that kind of 'ignorance is bliss' moment only happens once. Know what I mean?
Speaking of not knowing anything... with Oblivion, I already knew that I'd start in a cell, that the king would come down, that they'd escape through a passage in my cell, that I'd end up with the Amulate of Kings, that gates would start popping up all over the place if I started the main quest. I knew all of that before I even loaded the game. However, I did not know anything about the main quest. I knew nothing of any story lines at all. I pretty much just knew how the game looked, how the combat system was, that you can ride horses, that the AI was radiant, and other general things about the game. But outside of the opening happenings, I didn't know many specifics, if any. To me, that limited knowledge didn't ruin anything.
So I'm going to take the same route with Skyrim. I'll look at the pictures, read some reviews and watch some trailers. I'll stay away from all spoilers and info when it comes to plot lines or quest details. When I start playing, I'll be back to not knowing what I'm supposed to do, so I'll go out exploring a wondrous land, still blissfully ignorant to what lies beyond the next rise
